Although the plugin doesn’t include a map for Lithuania divided by its municipalities, we can use a custom geoJSON file to create a map. I tried to extract the shapes for the Lithuanian municipalities using QGIS and followed instructions on how to setup a custom map source.
After struggling a bit with missing region shapes from the QGIS export file, I ended up searching online for available geoJSON files for Lithuania and found a geoJSON file online in a GitHub repository.
I then hosted the custom geoJSON file on Github Gist to make it easier to reference it on the map edit screen.
This is an example that you can use custom geoJSON files to create maps and often you can find the source files you need online.
