Add-On settings not showing Smarthome/J Tuya Binding

Add-ons Bindings
1

Some time ago I install the smarthome/j tuya binding, did all the required things and in the end my tuya thing comes up and works.

Now I want to add a second thing. But the tuya binding is not listed when I want to discover the new thing:

Also under add-on settings the binding is missing:

Nevertheless the tuya cloud project thing is online:

Code:

UID: tuya:project:123456789
label: Tuya Cloud Project
thingTypeUID: tuya:project
configuration:
  accessId: 1234567890deleted
  schema: tuyaSmart
  password: 1234567890deleted
  dataCenter: https://openapi.tuyaeu.com
  countryCode: 49
  accessSecret: 1234567890deleted
  username: 1234567890deleted

So my question is: How to discover the new thing?

I noticed that the Tuya binding is not automatically installed when you update openhab.
Try installing the binding again.

Sorry for the late replay. I was busy working.

The point is, that the binding did not show up as an installed binding and there is no option to install the binding.

Nevertheless, the one tuya thing I have got is working with openhab.

Make no sense to me.
