There is no software or bot that can bypass Telegram’s invite protocol. Websites or apps claiming to provide access to private groups without links are almost certainly phishing attempts designed to steal your phone number, session data, or install malware on your device. The only way to enter a private group without a link is to be added by an existing member.
This only works if the group settings allow members to add other members. Some large or private groups disable this feature for security reasons.
If you are a member of a public channel, you can often join its private or public discussion group by tapping the "Discuss" button at the bottom of a post or within the channel's profile description.
