Hi there! Nope, is not possible to get the id/hash pair for private chats or channels via the joinchat link without joining first, all you can do is using messages.CheckChatInvite to get a brief description. You have to pass only the link hash as argument, which is GG4BlQwm19czcBGOewv40Q in your example.

However, if the chat/channel is public (i.e., you have its public username), you can get the id/hash pair by using contacts.ResolveUsername.

Edit: If the channel/group is public and all you have is just an invite link, you can use messages.CheckChatInvite to get the id/hash pair. The returned type will be types.ChatInviteAlready in this case, instead of types.ChatInvite

Not sure what I removed but most likely a mention or link to your library because I acted like that back then, but indeed this is extremely old.

In any case, the issues section in GitHub is only to report bugs or enhancements in the library itself. If you have usage questions, you should ask those in StackOverflow or the @TelethonChat group.
