Smb external share how should I typ the share?

Hi,
I’m trying to connect my smb share to my nextcloud.
What I have done so far is installing the apt smbclient package for my server that runs on Ubuntu and installed the external share application in nextcloud webgui.

So far so good.

Bu now, how should I typ the address etc?
I can’t for the life of me understand how.

When I login on our computer (windows domain) we write:
User: nohatech\calby
Password: xxxx

Then we’re in, and then to access the share we write “\storage\xxx” in the file explorer window.

So how should I write the settings in nextcloud?

I would love for someone to help me, we are going from seafile to nextcloud only for this smart function as we then don’t need to have two setups.

This should work right?

Well, In the same machine aldo in the terminal I can list all of the shares and I can also connect to the shares - so what’s the issue with Nextcloud?
This is the function that we need so without it my company and I will go back to Seafile.
