Every now and then this kind of requests pop up.
Those other providers don’t offer any tools or APIs for 3rd parties to integrate their catalog. There’s seemingly ways, few of them are legal. What might not be pursued for an individual will definitely not be tolerated if it’s attempted by another company.
Therefore…
duplicate suggestion as well as same as for most of those other threads (even if you “shy away” from asking Plex to play the 3rd party videos themselves)… that’s not going to happen
Closing this suggestion
