I've invested some time in making Ubuntu Touch apps available on more targets through an example Snapcraft project, starting right from the default C++ Clickable project and extending it by Snap Packaging.
This also allowed for the lomiri-ui-toolkit-core24 to grow, both in capabilities and correctness for a Snap environment.
If you also want to see more of your favorite Ubuntu Touch apps on the Ubuntu Desktop then go ahead and look at this example right here: https://gitlab.com/fredldotme/snap-packaged-ubuntu-touch-example-app/-/tree/main?ref_type=heads
Little fact on the side: The resulting .snap file is mere 32KB small, since everything else is mostly residing in lomiri-ui-toolkit-core24.
