Does not work in multidomain setup with TYPO3 10

I have a multidomain system and wonder how this extension connects the backend module to my site config because the typoscript setup is always empty even though I have added the typoscript constants and setup as described in the documentation.

What do you see when you access the Locallang Builder Backend Module? You should see it even without included typoscript.
Normally it should be sufficient if you assign the static template to the first microsite (root page)
Did you include the typoscript-stuff via "Template includes" or by including the setup.typoscript / constants.typoscript files?

I'm on TYPO3 10 and I just get an error message saying "Please include the "datamints Locallang Builder" static template." because it doesn't load the templates from the "Backend" folder.

I tried both ways but now I see the problem. My first page tree has no typoscript setup at all because it's a "global storage" and there is no website behind it. When I disable the "is_siteroot" in the page settings, the backend module works. Mysterious...

This is how my page tree looks like:

ROOT
|- GLOBAL STORAGE
   |- Frontend users
|- Website 1
|- Website 2

I still wonder how the backend module fetches the typoscript from the first "is_siteroot" page.
