Mobile: Tap bot message to reply and @mention that person on Messenger

[simeonlg]

Describe the solution you'd like
Tapping the webhook on mobile results in eg. @username (Full Name)#0000 to be copied to the message box, useful for quickly mentioning that user. If such a tag is given, it should @mention the person on Messenger

Additional context
#0000 could probably be rstripped off the string sent to messenger

The solution currently works if only full names are presented, but the #0000 is sent to Messenger which makes it look a little awkward. v5.0.3

Related to #447

Should be working in v5.0.0, but I'll test it.
