As stated in the thread below, the only way to do this with 3rd Party access to the Sonos API is to contact Sonos Support. I appreciate you mention you’ve already done that, but that still appears to be the only way forward to revoke access…
@mtnman I'm trying to understand what Samsung could do with the authorization that you wouldn't want them to. Or is it just the nagging feeling they could have access?

I don think the concern is really over Samsung, but more general. For example, as a result of my Sonos Alexa app I had the account tokens for many thousands of Sonos customers, in a database. If that database still existed and was hacked, and the hacker also got my app secret, they could issue commands to all of those customer systems to play stuff, send audio clips, mute everything, blast the volume, etc, and be exceedingly annoying.
The risk of this is reduced if Sonos customers can see who has been given access to their system, and revoke that access when required.
