perhaps this answer will help you:
at the end of the place of your message Link example: yoursite.com \ checkvisit.php? id = 1234
when a user opens an automatic communication channel for a telegram ...
you can understand that the message has been read
you must set in checkvisit.php to check db if id exists, not read, set it to read
then id in db remove or disable
but this method is simple - the telegram must add 1 parameter to return this
sorry my english is not good
