System integration for PNG and SVG file type support to allow "Open with" operation for Microsoft Store app version

Is your feature request related to a problem? Please describe.
I find it way more efficient to simply click on a diagram and get it opened as opposed to launch the editor, open file, browse your folders to finally find the file you are looking for and open it. However, it is not possible with the Microsoft Store app version (windows 11). For normal apps, you can always choose "Open with..." and locate your app and link them this way, but it is really complicated for Microsoft Store apps. First, they do not show up at all in the "Open with..." app list. Second, it is complicated AND not stable to locate them manually (I managed to do it once, and it worked for a couple of weeks, but now all of a sudden it stopped working, most likely because the OS moved the executable to a new location).

Describe the solution you'd like
It would appear that to show up in the "Open with..." app list, the Microsoft Store apps must register all supported file types somehow. I think the best way forward for the app is to register not only .drawio, but also .SVG and .PNG formats.
As an extended goal, it would be great if the system file type integration were accessible from the program's settings, but this is nice to have. Manually configuring "Open with..." once would be quite enough to unblock the situation, I think.

Describe alternatives you've considered
As described earlier, the workarounds include:

• opening from the editor (much slower)
• using non-standard ways to locate the executable (quite complicated + not stable in time)
• using .drawio files instead of PNG/SVG (I suppose ; not tested; anyway I love the "editable SVG" concept and using the .drawio format is a no go for me).

Additional context
