I have a document on my NAS (WD MyCloudEX2Ultra) in .odt format.
After opening this document, I try to insert a Section from the NAS, I select Link and Browse, and a dialog opens called “OnThis Computer”. It offers a Connect to Server, but when I enter "smb://mycloudex2ultra into server address, it doesn’t enable the Connect button.
I am able to access this smb share from KDE Neon, except from LibreOffice.
Is there another way to enable smb access?

BTW, this works on Linux Mint Cinnamon.
