Is our license information on mobile device allowed?

[FlorianK13]

Right now we show a button to the license information in our frontend for touch devices that opens a popup. Is this allowed? Or do we need to show some license information directly on the map?

Maplibre has a "compact" attribution mode, where the popup is shown on the first page load, but collapsed to a smaller icon upon user interaction with the map (https://maplibre.org/maplibre-gl-js/docs/API/type-aliases/AttributionControlOptions/). Might be a good solution for us as well?
