Hi @Romila baretto ,
If you want to get app list from tenant level, you can use this pnp PowerShell command.
Here's what I tested:
Connect-PnPOnline -Url "https://tenant-admin.sharepoint.com/" -Credentials $cred Get-PnPApp
If you have enabled MFA, you can Change the parameters from
-Credentials $cred to -UseWebLogin.
And I found a similar post for your reference:
