Google home app has a remote. Select the TV and you’ll see a volume wheel initially. Look in the bottom left corner for a button labeled remote. Mine asked me for a code and my tv popped up with the code to enter to pair and then I was able to control it.
I just tried it before typing this comment.
What about a mouse?
You can buy a Mibox remote on Aliexpress for 5 bucks and pair it with the TV no problem
