Answer 1

I have solved the problem. from "Account and import" add your group account then You can reference below code to test whether you can send an email in group account.

  var alias = GmailApp.getAliases();
  var num = alias.length-1;
  var myMail = getMyMail();

  if (num<0){
    return false
  }else{
    for (var i = 0;i <= num;i++){
      if (alias[i] == "yourGroup@Domain.com"){
        var myGroupMail=alias[i];
        break;
      }
    }
  }
  if (myGroupMail != "yourGroup@Domain.com"){return false}
  GmailApp.sendEmail(toEmail,strSubject,strContent,{from : myGroupMail});
