TuneIn PlugIn Installation - the final chapter explaining how to actually access TuneIn

[EBRJR1957]

I am not entirely sure what a "pull request" is. While I am a lawyer and can usually understand metalanguage which is not in my own field, I am not succeeding here. On my Plex Server for Synology, I have manually installed 9anime, Audio Addict, TuneIn and Webtools. I seem to have gotten the method down to add bundles and make plex see them.
My goal here is to get TuneIn working so that I can use my custom radio stations from DI.FM. TuneIn allows that and I am hoping through TuneIn, I will be able to play the DI.FM stations through the plex media server and my far flung plex clients. Loading DI.FM directly just seems too much of a stretch. Notwithstanding all writings to the contrary (indeed, they are presented almost as assumptions not requiring any explanation), there seems to be no way to add the TuneIn plug in through the WebTools. I had a fleeting hope that a "pull request" would provide me with the proper URL which could be recognized by WebTools to literally pull and install the plugin. It was a quixotic hope.

So, having manually managed to install what I believe to be the necessary plugins for TuneIn (at a very superficial level - meaning if there are ancillary settings such as where data should go, etc), I have not done that.
Having done all of this, there is no obvious way to interface with TuneIn in order to make the necessary adjustments (i.e., user account, user name, etc.) such that TuneIn will stream to me. Indeed, there is no obvious way to interface with TuneIn at all.
In short, following all of the advice and tech stuff as I was able and prepared the Synology plex server to the point where all the work should be paying off, I am missing that final chapter that would "bring it all home"! I have a radio that I cannot set up or play my music through.

If you could consider this "pull request" as a request for that final denouement/chapter/explanation that will suddenly illuminate all the previous prep work, I would be most grateful. Such an explanation might actually be a kind of "Rosetta Stone" throwing light (or, I would settle for a primer) on the thinking behind the metalanguage of these types of plugins.

Thank you in a advance.
