View - Missing Options - In the top-level folder

Hi everybody, I am trying to create filtered views in a document library. In this library i have about 200 folders.

My goal is to create personal views for my colleagues so they can see only the necessary folders to make their lifes easier.

I tried to filter the folders by name, but unfortunetley that does not work. Filtering by folders name does work as far as I can see just the relevant folders, however, the documents in the folder are not displayed, since the filter is applied on the documents once I click in the folder.

Does anyone have an idea?

I found some additional info here: https://answers.microsoft.com/en-us/msoffice/forum/all/modern-sharepoint-library-view-settings-folder/56fda4ba-c463-43d4-91d9-555d27d9d83d
