How to sell other people's subscriptions to paid telegram channels through your website (or bot)?

Question

Bots

Good afternoon.
I have a goal so that a visitor to my site can pay for a subscription to someone else's closed (that is, paid) channel in the telegram.
The only option I see is the creation of a personal account for the administrators of such channels, where they will post their invite links. And after the user of my site replenishes the balance, he will see this invite code. But if the subscription expires in a month, how can I make sure that the administrator automatically deletes those who did not renew the subscription?
Are there any other options? like a bot via telegram?

The bot can remove users from the group.
Invite links for users who have paid for access must be masked with a hidden redirect.
