I have SharePoint Team Site Administrator-level permission. I don't have AppCatalog site permission and I don't have SharePoint Administrator-level permission.
I need to add the PnP Modern Script Editor app to the SharePoint Team Site. My user is in the Owner group of that site.
Is there any alternative to adding an app to my site without adding the AppCatalog site collection?
Thanks
You could use site level app catalog: https://learn.microsoft.com/en-us/sharepoint/dev/general-development/site-collection-app-catalog
More precisely, you can ask your tenant admin to create one for you, and then you will be able to manage apps in your app catalog yourself. In particular, add that app to your own app catalog.
