Just upgraded my `wsl` Ubuntu distro to 20.10 "by hand"; the start menu entry name remained "Ubuntu 20.04 LTS" and I would like to rename it accordingly. How to do it?

The problem is that this is one of the start menu entries (along with e. g. Cortana, 3D viewer and several others) which do not have "Open file location" in their context menu, only "Pin to taskbar", "App settings", "Run as administrator", "Rate and review" and "Share" (and I could find nothing useful for my purpose under "App settings"). They do not even seem to come from any .lnk file, at least I cannot find such anywhere on my system (using [Everything](https://www.voidtools.com/)). I am able to create a link to these startup entries elsewhere (say, on the desktop), and I am able to rename this desktop link, but understandably this does not affect the start menu entry in any way. Looking at properties of such newly created links, their `Target type` and `Target` is described by some obscure text which does not even entirely fit in its window:

I tried following the paths which contain these texts, there are several, but I could not find any links there to rename. As you see, "Open file location" is greyed out.

So, how can I rename such start menu entry?
