Connect Mikrotik hAP ac² to pfSense end point

I have 2 computers that connect to to a pfSense endpoint using OpenVPN. For each computer I defined a user and applied the scripts / config I download from pfSense.

I would like to install a Mikrotik hAP ac² and use it to establish the OpenVPN connection to the pfSense. The traffic would be routed such that internet traffic would go out over their internet while traffic to the other endpoint would flow through the Mikrotik.

Is there a guide I can follow? With the pfSense I can download the script and all I have to do is run it. Is there a way I can adapt this to the Mikrotik?

Thanks

The easiest way to set up hAP ac² as a client would be IMO with a .ovpn file
