Activiation of ZBT-1 network settings missing, no json file

I am currently setting up my Home Assistant for the first time (bought HA Green). Most things went smoothly, but when I plugged in the ZBT-1 USB dongle and then started the adding process inside the HA interface, I might have mistakenly clicked on something and was thrown out of the process.
Now when I click on the ADD button in the HA interface, a dialog pops up asking me to upload a manual backup:

Restore your network settings from an uploaded backup JSON file. You can download one from a different ZHA installation from Network Settings , or use a Zigbee2MQTT coordinator_backup.json file.

But I don’t have a backup or anything. But without this, I could not proceed.
I also took out the USB dongle and put it back in after a brief wait, but that did not fix the problem.
I then restarted the HA Green via the HA interface, but now I get nothing – when I go to the devices & services section, the ZBT-1 is not displayed anymore…
What should I do?

Sorry for the noise – fixed it myself. So I’ll at least try to document what needs to be done for others:
I needed to manually add an integration in the devices and services section, then select Zigbee, and when I did that, the interface suggested a path for direct connection to the ZBT-1, which I chose. Then came the dialog where I misclicked last time (I clicked on restore instead of set up a new). Now I chose the correct option and that successfully added Zigbee Home Automation (ZHA) to the devices and services section.
All good & thanks for your patience. :slight_smile:
