Question

I openend this issue in the m365 cli github and @waldekmastykarz suggested that maybe this is because an API limitation. Defininetly not something they can help with in the m365 cli or PnP.PowerShell group, which are the two different approaches I tried.

Is this indeed an API limitation or are we missing something?

Environment details (development & target environment)

• Your Developer Environment: Windows 10
• Target Environment: SharePoint Online
• Tooling: PowerShell with m365 cli and PnP.PowerShell

I've also observed this behaviour attempting to retrieve the list of SPFx permission grants using either M365 CLI or PnP.PowerShell, using an app-only identity with certificate
