from what I understand it’s running Android and you can install apks to it.
I found this video helpful: https://www.youtube.com/watch?v=rKXJ8PYkdf4
Seems they use Google Chrome as well on that device.
So you could try the spacedesk app via installing its apk and/or get a browser and try to connect via HTML.
Would like to know what worked for you if so.
