To add a bot to a group we can use this link:
https://telegram.me/[botname]?startgroup=foo
It shows up a dialog to select a group. But when the bot is added to the group a start command also gets added like this:
/start@[botname]
The problem is that group members will keep tapping on this start command and it will be awkward.
How to simply add a bot to a group without a clickable command link? Isn't there any other deep link?
