Getting the owners for all SharePoint sites in tenant using Powershell

Hi everyone,

I'm trying to retrieve all SharePoint site groups along with their respective owners, members, visitors, and guests. While I can see visitors from the admin center and SharePoint admin center, my script encounters "access denied" errors when I run it. Interestingly, the script works perfectly on a test site where I've given our admin account site admin access.
Currently, I am trying to get owners, members, guests, channels, sharepoint site list from Teams and visitors from sharepoint using Get-SPOSiteGroup. I am getting every info instead of visitors if i run a loop. If i run a script for a particular site then it gives the visitors easily.
Is there a different parameter I should be using, or is my approach incorrect for retrieving visitors from Teams-enabled sites? Any guidance or suggestions would be greatly appreciated!
I've put my question on another discussion
