For a instance, if a tutor already have a zoom account (xyz@gmail.com) and tutor signed up the platform with abc@gmail.com. Here when a tutor receives zoom invitation link, he is provided with the option to switch the account (either xyz@gmail.com or abc@gmail.com).
When a tutor switches the account (from abc@gmail.com to xyz@gmail.com),then all the notifications will be sent to the zoom account which the user switched to i.e. in this case, xyz@gmail.com.
