RB911 point to point

Hello,

I have two routerboads rb911 5G, I have installed winbox and try to connect both routerboards one by one.
The works well but I do not know how to configure the wlan interafce 5G between both of them to send and receive files, video, images?
I am very new to RB911.

Please let me know if an example exist already.

Many thanks in advance.

Best regards,

VB
