What is Tenant appcatalog?
A constant centrally located SharePoint online site utilized to deploy all add-ins and SPFx solutions with Tenant administrant consents.
The solutions located here will be accessible for all site collections across the company and each site collection administrants can add them to their site collection.

beforehand this app catalog was fluently findable in the navigation, but after SharePoint admin center site ultramodern look it’s hidden under “ More features” –> “ Apps”.
And if you don’t have one you can create a tenant app catalog from this screen.
What is Site collection appcatalog?
This new app catalog allows us site collection administrants to plant solutions at a site collection level. Similar deployed solutions won’t be available

Connect-PnPOnline -Url https://<tenant>-admin.sharepoint.com -UseWebLogin
Add-PnPSiteCollectionAppCatalog -site https://contoso.sharepoint.com/sites/marketing

Once this appcatalog is created you could see a list titled “ App for SharePoint” is created inside your site collection
So, way to go for site collection restricted solutions, and site collection administrators can manage it.
How to remove site collection app catalog?
We can remove the site collection app catalog by using the below PnP PowerShell script.
Remove-PnPSiteCollectionAppCatalog -site https://contoso.sharepoint.com/sites/marketing
