set
Use this method to set default chat permissions for all members. The bot must be an administrator in the group or a supergroup for this to work and must have the can_restrict_members administrator rights. Returns True on success.
Parameters
Unique identifier for the target chat or username of the target supergroup (in the format @supergroupusername)
A JSON-serialized object for new default chat permissions
Pass True if chat permissions are set independently. Otherwise, the can_send_other_messages and can_add_web_page_previews permissions will imply the can_send_messages, can_send_audios, can_send_documents, can_send_photos, can_send_videos, can_send_video_notes, and can_send_voice_notes permissions; the can_send_polls permission will imply the can_send_messages permission.
