Unable to Change Permissions on Folders for Access over WiFi

I have a MacBook Pro M1 2020, and when I connect to this MacBook Pro over my local WiFi network from a different Mac, I am unable to access the data in my Desktop, Documents and Downloads folders - when I Get Info it says these folders have custom permissions. I have attempted to manually update the file permissions for these folders to allow for complete read and write access for both my registered user, as well as for Everyone, but this has not resolved the problem. Can anyone help me learn how to change these permissions to allow for full access? Thanks, Dan
