Feature request: Share your public key with a clickable url to add a user to your companion

[HenrikBo]

I would be a great feature if you could share your public key in the public or any of the other channels, with a clickable URL to add the user to your companion.

Workflow

• In the channel click share your contacts (New feature)
• Client will broadcast a link like meshcore://{client ID}
• The receiver can click on the URL in the channel and add the user to the companion.
• It should automatically save the path it came from to allow direct DM

The advert content is too large to be sent in a channel as a flood message. How would you propose to do this?
