Using logic control {Math.random} while making a fantasy team selector

Math.random allows us to randomly generate numbers using JavaScript. We can use these to our advantage and make really cool stuff. Recently I have been working on making a fantasy team generator which will basically generate a random fantasy team for us to bet on. I think that this is a very good project. The problem that I have is that I am unable to apply the required logic for it. Let explain this brief.

Points to be noted while making a team: 1.) There can be only 11 players in your team. There 22 players to select from 11 from each team. 2.) You can only have at most 7 players from a single team no more than that. 3.) You can only have 1-4 wicket-keepers, 1-6 batsmen, 1-6 all-rounders, 1-6 bowlers. 4.) You only have a maximum of 100 points each player carries a different point value one player maybe worth 10 points while one can be 7 points. These points are pre-defined. 5.)We want to keep all the above points into consideration while using Math.random() to generate our random team.

The problem I faced: --> Not able to apply logic for the 3rd condition.

We have been given specific ranges for particular roles of players now I have thought of most of the thing but I am not able to figure out how can I tell JavaScript to stay in these ranges while using random method.

Solutions that I thought of: --> Make an array for every possible combination and then randomly select one from the array and then make our team accordingly. for e.g.) const combinations = [..., [2, 1, 2, 6],...]//this can be a possible combination the combination can work because the total no. of players being selected are 11. --> Keep on calling the function until the answer is equal to 11.

What I want as an answer: --> A way to tell JavaScript to stay in those given ranges while using random method the total no. of players should 11.

What I have until now(I am still working on other things but this will help you get an idea of what I am doing):

const bangalore = [
   {
      Name: "Pavan Deshpande",
      Type: "All-rounder",
   }// example of how i have made players
//Total 22 players in this team

];
const chennai = [
   {
      Name: "MS Dhoni",
      Type: "Wicket-keeper",
   }//an example
];
const delhi = [
   {
      Name: "Rishab Pant",
      Type: "Wicket-keeper",
   }//an example
];

function addPlayerToList(listNum) {
   switch (document.getElementById("playingTeam" + listNum).value) {
      case "bangalore":
         for (let player of bangalore) {
            document.getElementById(
               "playersList" + listNum
            ).innerHTML += `<li id='playerOfTeam'><button id='selectBtn'>✔</button>${
               bangalore.indexOf(player) + 1
            }.) ${player.Name}<br />${player.Type}<br /><br /></li>`;
         }
         break;
      case "chennai":
         for (let player of chennai) {
            document.getElementById(
               "playersList" + listNum
            ).innerHTML += `<li id='playerOfTeam'><button id='selectBtn'>✔</button>${
               chennai.indexOf(player) + 1
            }.) ${player.Name}<br />${player.Type}<br /><br /></li>`;
         }
         break;
   }
}
document.getElementById("playingTeam1").addEventListener("change", () => {
   addPlayerToList("1");
});
document.getElementById("playingTeam2").addEventListener("change", () => {
   addPlayerToList("2");
});
