The number of applications in front of you or your position in the queue/

Good day. Tell me how to implement it:
In the notification to the request author - specify the number of requests with the New status. Optimally, count by group, but you can by request category.
Apparently, you need to create a variable - so that it can be inserted into the text using $ ?
for example - Here is a standard notification.
Dear ${requester.name},

This is an acknowledgement mail for your request. Your request has been created with id ${id}. The title of the request is : ${subject}. The status of the request can be tracked at $RequestLink .
And we want to add -
In front of you in the group - ($) requests in the queue.  Your position in the queue  ()  * Or your request № ($) in the group queue.
$AutoSuggest
Please get back to us for any further clarifications.

regards,
Sys Admin team.
