Need Help for Routing

Hai,
First of all I’m a new to Mikrotik, so I need your help guys.
My problem is (see the diagram) I want to give access the hotspot client (192.168.5.0/24) to the intranet server (192.168.4.2/24), how do that ?
help me with step by step clue .. script is not necessary but if you don’t mine, I appreciate that.

Thanx

Do they still need to log in, guessing not. In winbox go to IP - Hotspot - Wallet Garden IP List and add a rule with 192.168.4.0/24 s the Dst-Address
