How to set up Arduino IDE for RePhone

I understand how Arduino IDE works for WIO Terminal, and Arduino UNO boards.
There is a Folder for the libraries and a Folder for the Code Project
It appears that RePhone is different?
I discovered that there are no ZIP files to import via Arduino IDE. Do the required libraries stay with the Folder containing the .INO files or a general Library folder? If so, how does RePhone .INO know where the Folder is?
I just had an opportunity to inventory my Kickstarter purchases and found out RePhone is DISCONTINUED! I was hoping to salvage my investment somehow. It would be nice to know if someone has found a way to attach RePhone modules on Arduino UNO boards and Grove shields, or possibly WIO Terminal.

I am just a NOOB and learn by example, mostly
