I dont want to access ssh just the interface of AR750S while I am connected to my main router.

Most times I don’t directly connect to the AR750S (from my phone or pc). It runs a wireguard client and powers my android/tv/roku for streaming services. If I need to change anything or check the status of connections, I first need to connect to AR750S wifi-AP and then access the interface. I am trying to avoid that. This was actually possible with the AR300M and the old FW 2.2x
