SMB share with hidden files and directories not visible

Hello,

newbie on TrueNAS Scale looking for support.

I installed and set up a fresh Scale 24.04 with datsets and shares etc.
There are two Groups (admin 3000, ks 3001) and two Users (admin 3000, ks 4001) only.

I downloaded as admin into one of the SMB shares some files+directories via shell using rclone, and LSing that share I can see the downloaded files are there.

That share is accessuble too via Linux/Mac desktops, and I have read/write privileges on that SMB share, but the files I downloaded via CLI are not displayed.

i suspect some kinda of permissions issues; looks like the files I downloaded with one user (admin) into that SMB share are hidden to other user (ks).

Can someone provide some hints to drive me in the rigth direction to fix this?

Tkx.
