Share unencrypted Cryptomator files with Samba

Cryptomator version: 1.5.15 (appimage-176)
System: Ubuntu 20.04

I have created a Cryptomator valut and added some files.
Now I want to share those un-encrypted files on the local network, but only when the valut is decrypted.

Samba was setuped following the steps in this link:

I tried both, “automatic pick a suitable location” and “custom path” option. In both cases, the other computer (also Ubuntu 20.04) didn’t find them.
Normal files could be found, but not decrypted files over Samba.

Is there a way, so I can access my un-encrypted Cryptomator files over Samba with my second Ubuntu 20.04 computer?
