how to launch the tor browser from a snap install?

Trying to launch tor I get prompts to install with apt whereas I’m using snap:

thufir@dur:~$    thufir@dur:~$   tor  Command 'tor' not found, but can be installed with:  sudo apt install tor  thufir@dur:~$    thufir@dur:~$   torbrowser-launcher  Command 'torbrowser-launcher' not found, but can be installed with:  sudo apt install torbrowser-launcher  thufir@dur:~$    

This is after just installing tor through snap, as below. How is the browser launched?

thufir@dur:~$    thufir@dur:~$   sudo snap install tor  snap "tor" is already installed, see 'snap help refresh' thufir@dur:~$    thufir@dur:~$   snap info tor name:      tor summary:   Anonymising TCP overlay network publisher: Iain R.

I would naively hope that the snap install for tor would include the browser launcher. Running Cosmic:
