How to transfer an application (windows store ecosystem) from one computer to another?

Question

Windows

Windows 10 x64 system
There is a very small but proud DI.FM unofficial client application (it turned out to be much more convenient to listen to music from DI.FM under Windows than through the site).
Developer: djbiomc.com I
used to download and install an application from the Windows Store without any problems, but at some point it disappeared from there without explanation. ( https://www.microsoft.com/en-us/store/p/difm-unoff... )
There is a need to reinstall the system, therefore, install the application again.
I didn’t google the application distribution kit (it’s not an android, where everything is at least on w3bsit3-dns.com)
Access to the C:\Program Files\WindowsApps folder is obtained, I see 3 folders with the desired application: https://i.imgur.com/8MKSuCq .png
When copying the application with "handles", it swears at startup: https://i.imgur.com/MnI0SN0.png
How can I now pack all this into .Appx and is it possible? (and what to pack from 3 folders)
Or how can I manually register it on another laptop to run it?

Answer 1

The developer suggested where kind people posted the distribution kit:
