Add herotag to address

[Petrica Butusina]

Description of the issue:

When you get a transfer from a herotag you don't have in your address it would make sense to simply click in the transaction page on the tag and add it if you want in your address. Right now, you have to search it and add it.

Steps to Reproduce (add as many as necessary):

1. Launch Maiar 

2. Click on received transaction

Maiar Version (See the About Maiar page in the Settings menu): Maiar release - v0.1.81

Additional information: I'm using iOS 14
