Nest Hub on-screen keyboard not registering input when using catt

Hi, As Home Assistant user, I successfully (and persistent) cast Music Assistant to my Nest Hux (Max). So essentially I cast the url like https://192.168.x.x/xxxxxx_music_assistant/ingress to the Nest Hub using catt. The Music Assistant (https://www.music-assistant.io/) interface allows search for Artist/Album etc, and on press, the Nest Hub on screen keyboard appears. However the on-screen keyboard is not registering any input at all. Is this a general restriction when using catt or something specific I could resolve? Any feedback would be welcome!
