Samba Share and file permissions

Configuration
1

Hello everyone.
I have installed Home Assistant OS in a Proxmox VE and it works great.
I have installed and configured Samba Share and I’m able to mount:
/config
/share
/backup
on my Linux Mint pc with autofs… so far, so good.
Now the point.
The file permissions on Home Assistant OS shell doesn’t look the same on my Linux Mint mounted folder.
Here an example:
Home Assistant OS shell:
-rw-r–r-- 1 root root 0 Mar 11 19:19 prova.txt

Linux Mint shell:
-rwxr-xr-x 1 ignazio ignazio 0 mar 11 19:19 prova.txt

Basically on Home Assistant OS, all files are created with 644 permissions while I see them on my Linux machine as 755
What is annoying to me is the executable flag so when I try to open a text file in my Linux desktop, it ask always if execute it or show it in a text editor.
Is there a way to mirror original file permissions into mounted shell?
Hope is clear.
Thank you.
Ignazio

Update.
To use chmod is still impossible but i was able at least to change the permissions of the shared files.
It was enough to mount the shared folder in the linux Mint machine using the option:

file_mode=0664
