As far as I understand, airmap uses only vector tiles.
The current version of Online Maps does not support vector tiles, so there is no way to use this.
If someday Online Maps can work with vector tiles (this is not a promise), then this can be used.

Unfortunately, I don’t know how to use this plugin in Unity.

If not, what would be the best course of action in order to use airmap plugin into unity ?

Any help would be appreciated
