Podcasts app *starting* unexpectedly

Recently I have observed the Podcasts app *opening* unexpectedly on my mac, roughly once a month but with no pattern I've been able to identify. This interrupts me from doing what I actually want to do, so I want to prevent the app from opening. As I do all my podcast listening through my phone, I would be happy to delete the app from my mac, though this appears to not be possible — there no "Move to Bin" option in the contextual menu for most of the pre-installed Apple apps, and the File > Delete Immediately menu item is disabled. Given my goal is to stop being interrupted, any suggestions why might the app be opening without any apparent action on my part, *or* how can I delete the app from my mac? - Preferences > Users & Groups > (me) > Login items is empty - Preferences > Keyboard > Shortcuts does not list any keyboard shortcuts associated with Podcasts.app - MacOS 11.6 (20G165) - Podcast.app 1.1.0 (1575.1.2)
