#[Solved] Struggling to pair Bilresa remote via Matter over Thread

Attached video of trying to pair. I'm holding down the middle button on the remote until the LED blinks red. On the phone, it just sits there forever.

I'm... unsure if I set up Thread correctly. Detailing the steps I went through:

This is on a miniPC with homeAssistant Core install via systemctl on Ubuntu. The miniPC has no wifi and is connected to the router via ethernet.
I've set up the matter server and it successfully connects to devices via matter over WiFi.
These Ikea Bilresa remotes are the first thread devices I've tried.
Tried instructions as best I could from various sources such as this page and asking different AI sources.
Picked up Sonoff Zigbee/Thread USB Dongle. It came with firmware for Zigbee. Flashed OpenThread 2.4.4 firmware via Sonoff Dongle Flahser site.
Set up OpenThread Border Router using the native install guide. I think I got the router service running properly eventually - but the next 2 sections in the guide (Form Thread Network and mDNS Discovery) were confusing to me.

Added the Thread Border Router REST API URL (127.0.0.1:8081 - I think that was the correct port)
Then went to Settings > Matter > Developer Tools > Set Thread Credentials and then pasted in the Dataset string returned by sudo ot-ctl dataset active -x
Then, on the Android phone, went into Settings > Companion App > TroubleShooting > Sync Thread credentials.

Then tried to pair.

Happy to share any more details or log files.
Help would be appreciated lol

Found this thread

Probably should've gone into #1284966617670881350 with matter tag, I see some threads about similar topics there

Update:
Successfully paired the remote.
I needed to enable ipv6 on the router and then enable ipv6 on Ubuntu.
