Setting lan to DHCP client

I'm building and testing Proton VPN on a OpenWRT raspberry pi 4. My internet connection is going to be windows 10 sharing it's wifi via ethernet. Windows 10 becomes a dhcp server when you share your internet connection.

I having a huge brain fart or its been a while since using openwrt gui, but I'm unable to find how to make lan interface a dhcp client.

Thanks in advance for the help!~
