Microsoft Graph PowerShell SDK Module OneDrive Folder Permissions Assignment

As an M365 Global Admin, I have been tasked with creating a new folder in other users OneDrive root folder (Documents) we can call that folder 'myFolder', then I need to assign a Microsoft Azure Security group ('myGroup') to that folder with read/write permissions. I have a list of users (taking input from txt file of UPNs), and am able to loop through the users and create the folder, so step one is possible, but where I am failing is the assignment of the permissions, am using PowerShell 7 and the MS Graph PowerShell Mod, actually for the folder creation I used the API and invoke-method, but I am running into problems since OneDrive is on top of SharePoint, I am not sure how to accomplish this task. Any help would be greatly appreciated!
