Galaxy Tab S5e not connecting

I want to use my new Galaxy Tab S5e with Processing and it’s not showing up as a device in Processing.

I’m using Processing 3.5.3 with Android mode 4.0.4 installed. I’ve turned Developer mode to “on” on the tablet by hitting the build number a few times. I think the USB drivers and SDKs are up to date. Do I need specific sketch permissions to access the tablet?

I’ve written a simple program and it runs on my PC but can’t connect to the tablet. Windows 7 recognizes it.

Any ideas why I can’t connect?
