You cannot remove the whole group if you aren’t an administrator of a Telegram group. Only registered administrators of Telegram groups can make any changes to the group chat. The group may not be deleted by moderators, and members are not permitted to delete it themselves.
When you delete your account, all of your messages and contacts are deleted as well. Groups and channels that you’ve established are orphaned, with no creator but administrators keeping their rights. As a result, even if the channel owner’s account is canceled or self-destructs, the channel does not automatically disappear.
A ghost profile picture is used to indicate that an account has been deactivated. As a result, other users may identify such a presence on Telegram simply by viewing it.
When you delete your account, Telegram claims that it deletes all of your conversations and data. Your account is permanently canceled, and your communications as well as contacts are irretrievably deleted.
It’s simple. Go to the file menu, then click telegram files (audio, video, and documents). You may delete a film from a telegram video file.
