Lidl sell some quite sophisticated kit. Don't they have some tech support?

I didn't find any support website.
Anyway in this video

almost near the end I see that they can change network config.
on mine I obviously trid clicking there, but nothing happened.
tonight I will try using a different browser, maybe MS Edge is the problem...
