Can one define a Google Chrome App as default app for a filetype?

I would like to define a Google Chrome app (aka. Google Chrome extension) called "Readium" as default handler for .epub files (an ebook format), because I consider it better than Edge (which handles these files by default) for this purpose.

Now, I was able to define Chrome as default app for epub-files using the option "Search an other app on this PC" and pointing it to

Code:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"

but that only starts Chrome which then has no clue how to handle that filetype.

I would need to be able to enter a whole commandline here (one can start Chrome's Readium extension directly using a commandline with some options, i.e.:

Code:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"  --profile-directory=Default --app-id=fepbnnnkkadjhjahcafoaglimekefifl

... but the dialog did not accept that line as a valid application.

I then tried to add the above command-line to the .epub filetype's OpenWithList in the Registry, i.e. under
"Computer\HKEY_CLASSES_ROOT\.epub\OpenWithList" but that didn't work, either.

Any idea or suggestion how to convince Windows 10 to accept Readium as a default application for .epub files?

Trying again with the "Search an other app on this PC" option this time the dialog accepted my entered command line, i.e. I entered:

Code:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"  --profile-directory=Default --app-id=fepbnnnkkadjhjahcafoaglime "%1"

into the dialog and this time this was accepted as "application".

Now, double-clicking a .epub file firectly opens Chrome's extension Readium with the double-clicked document loaded.
Happy camper now...

PS: Note the added trailing "%1" in order to pass the document's path as argument to the application
PPS: The funny app-id one can find out by choosing "create a shortcut" on the desktop on the chrome-extension and copying that line from the properties of the created shortcut..
