Amazon / Woolley Zigbee plug

This is probably a long shot, but has anyone got one of these Woolley plugs?

I have set one up via the Hue app, and it works…ish
I cannot get it to show in HA (via Hue integration) and nor does it appear in the Google home app.
And the Led is constantly flashing blue!
I cannot find any documentation for it
Other generic Zigbee plugs, e.g. LedVance, show up in Google Home, and in HA, and can be controlled

Just hoping someone can help.
