Serviio and disks via Thunderbolt & USB

Hi everybody,
I use Serviio since years on an old iMac 2011 and today I installed Serviio on my new iMac under Catalina (macOS 10.15) which uses external disks via Thunderbolt & USB.
These disks are not seen in browsing for shared folders. Only the internal SSD and a disk connected via Firewire (with adaptors) are seen.
I wanted to test with install Serviio 2.0 but Serviio Console seems to be 32 bits and doesn't appear in the Apps folder.
Even if Thunderbolt was not handled yet, that doesn't explain why USB disks (directly connected to the Mac) are not seen. And doesn't explain too how a Firewire disk, connected via thunderbolt (the iMac has no FW native) is seen.
Perhaps I forgot to do something

Edit : I was wrong and Console 2.0 isn't 32 bits. Simply it was not installed when installing Serviio 2.0 and I was able to copy the console from a Mac to the other. Now I run Serviio 2.0 with Serviio Console, and I have the same problem of disks which are not seen by Serviio on this Mac.

Edit 2: I finally found a workaround in these forums:

The Serviio console is now web based, so there really isn't an app for it. You just need to go to http://localhost:23423/console with a web browser on the Serviio computer, or from another computer on the network, substituting localhost for the actual computer name or IP address.

And as you discovered, accessing external drives from the MacOS requires changing permissions for Java. Hope you have everything you need now to get everything working correctly.

Yes, thank you. Since I followed the method to authorize java, all works well
