Developer Terms..

Achieved this using webRequest.onBeforerequest..

Explanation :
When you enter link (similar to below one ) it will open with default google account.

1 https://meet.google.com/xxx-xxxx-xxx

After switching account the link changes to some thing like this

2 https://meet.google.com/xxx-xxxx-xxx?pli=1&authuser=y

here y is your google account/user number as per accounts in chrome. Chrome numbers your accounts starting from 0.

So Whenever link corresponds to meet (similar to first link) redirect to changed link(second one)

chrome.webRequest.onBeforeRequest.addListener(function (tabDetails) {
            var tabUrl = tabDetails.url;
            var req_url_extra = "?pli=1&authuser=" + googleAccountNumber; // user input
                var redirect_url = tabUrl + req_url_extra;
                return { redirectUrl: redirect_url };
             }
            , {
                urls: ["https://meet.google.com/*"],

              // https://meet.google.com/* is
              // regex for google meet links

                types: ["main_frame", "sub_frame", "stylesheet", "script", "image", "object", "xmlhttprequest", "other"]
            },
            ['blocking']
        )

This handles most of the cases.. But in cases like this

3 https://meet.google.com/xxx-xxxx-xxx?pli=1&authuser=z

• User desired mail is y but url is related to z To handle these type of cases we need to do modification to our prev code..

  chrome.webRequest.onBeforeRequest.addListener(function (tabDetails) {
            var tabUrl = tabDetails.url;
            var req_url_extra = "?pli=1&authuser=" + googleAccountNumber;
              
            //?pli=1&authuser=y required addition to link
  
            // check if ?pli=1&authuser=y is there in input link
            // if it is there then no need of modifying link
            if (!tabUrl.includes(req_url_extra)) {
              // to handle case 3 https://meet.google.com/xxx-xxxx-xxx?pli=1&authuser=z
              // check if ? is there in link
              // presence of ? indicates link of type 3 
                if (tabUrl.includes('?')) {
                  // removing ?pli=1&authuser=z part
                    tabUrl = tabUrl.split('?')[0];
                }
                // adding ?pli=1&authuser=y 
                var redirect_url = tabUrl + req_url_extra;
                return { redirectUrl: redirect_url };
            }
            else {
  
                return { redirectUrl: tabUrl };
            }
  
        }
            , {
                urls: ["https://meet.google.com/*"],
                types: ["main_frame", "sub_frame", "stylesheet", "script", "image", "object", "xmlhttprequest", "other"]
            },
            ['blocking']
        )
