Desktop files and mime types for Appimages

I downloaded Libre Office Appimage for Linux. Running it directly is no issue but there is no desktop files or even mime type configuration. Because of such issue right click > open as doesn’t work. Are there ready made desktop files available. I don’t want to configure each of them manually. Also I have no idea how to associate filetypes with an Appimage

Appimage is a portable version of LO. It could be installed together with a “normal” desktop version. What would happen when trying to connect appimage with the filetype, when appimage has been moved to another system?

Use the “normal version” to get a version which connects filetypes to a program, which is really installed on the system.

Google may help - here described for Incscape:

And be careful. You, as administator of your system, have decided not to use the installstion your maintainer for the distribution may have prepared, so you can’t directly use the standard recipes. Always check, if descriptions fit for your system.

Appimage is provided by official downloads so it’s not unreasonable to expect mime type associations.

I had the apt install on my system but decided to swap it for Appimage as it was lighter because of disk space reasons.
