Wireless Access Point

I have a hap lite mikrotik (Mikrotik RouterBOARD RB941-2nD) and I need to make it act as an access point. The problem is, I am not able to run an Ethernet cable to the mikrotik so I need it to wirelessly connect to the main router, and then act as an access point.

Is there a way to do this? I tried searching but nothing I found works completely wirlessly and needs the mikrotik to connect to an Ethernet cable.

You will need to configure your device as a Wireless repeater.
