(Telegram is a chat service with an open API, their official web client can be found here https://web.telegram.org/#/login)
I'm in possession of a telephone number that has previously been used by someone else to register an account with telegram. Without infringing on this person's privacy I would like to re-register the number with Telegram for my own use.
Telegram accounts can be deactivated (https://my.telegram.org/auth?to=deactivate) by requesting a token which is send to a telegram client. The straight forward solution would be to sign in using an SMS token sent by Telegram and then request a termination token. However this would also give me insight into any conversations of the previous user of this number.
Is there a way to re-register this number without violating the previous user their privacy?
