How to add InfoWindow without a Marker using @capacitor/google-maps in React

I’m using @capacitor/google-maps and want to add an InfoWindow to the map (without marker), the examples online are all in AngularJS and using JS SDK Google map marker InfoWindow - Ionic | Christian Engvall. I can only find Marker API in @capacitor/google-maps documentation.

I have the same question. It appears this hasn’t been implemented yet?
