How do I have pifi work not plugged into router?

Just as title but how do I pair over wifi and keep the pifi network too

Doesn’t let you in app so tried with luci but it’s dropping altogether so I’m restoring via CLI

Raspberry pi doesn’t have two radios to AP+STA. So basically can’t pair and broadcast at same time. But pifi kit works for this. Don’t think possible without. Maybe if similar wifi adapter but kit works well
