Tricks to Make Ubuntu Apps Run On PureOS?

I have an app that is designed to run on Ubuntu. It works in a Solus VM. It doesn’t work in PureOS.

This app needs full access to all USBs to make it useful. I couldn’t get it to see all USBs in the Boxes VM.

Any other tricks to get it to work on the root PureOS?

What format do you have it in? Is the source code available?

What is the application? Also can you provide a link to the application website if there is one?
