Show a toast/notification if the url was loaded by companion

[whizzzkid]

Is your feature request related to a problem? Please describe.
When companion is enabled, the redirection happens silently, we would like to have an option to enable a notification if the current url is being loaded by companion.

Describe the solution you'd like
A toast might be too intrusive, a badge on the companion might be more easier from ux point of view.

• The icon indicator idea seems to overlap with Add an indicator to show that resources have been loaded over IPFS #662
• The idea of interstitial page that acts as a splash screen is tracked in Loading screen for non-local and redirected content #727

Feel free to provide comments in above issues.
