How to use Client id and certificate in PNP Powershell for SPO with Delegated permissions in Az APP

Hello everyone,

I have created an Azure AD APP with Delegated permission on SharePoint All Sites.FullControl, I have provided the FullControl to AD APP on SP Site Appinv page, but when i am trying to login using Connect-PnpOnline PowerShell using Client id and Certificate, it is giving me 401 error, and when i assign Application permission it works fine,

How to use the Certificate with Delegated permissions ? because delegated permission works fine with Cleint Secret but not with certificate and Connect-Pnponline giving warning for Legacy authentication with secret. Please suggest some solution
