Can't use input button with Google? (Nabu Casa)

Hi,
Am I wrong that neither scenes nor input buttons get synced to Google?

The following is screenshot from the HA Cloud config (nabu casa). They are all set to sync, but none of the “scene” actually do. The create errors in google (cannot connect to Nabu Casa)


Out of those only the “OnOff” (which are linked to helpers - input toggle in HA) show up.
What I find strange is that Nabu Casa sees input buttons as “Scenes” and not switches or something.
The “Off to work” ones are what I’m testing and only this shows up.

Again, strange from Google this time - it shows as “offline” but it’s not actually. I can call it, and it reacts…

For info - My system runs since a couple of years an has 100+ devices - 50 or so are synced to google. I’ve also set the IPV6 off as recommended somewhere by Nabu Casa. I already noticed this behavior of not syncing 2 years ago.
