How do I mount a USB SSD drive and share across the network?

I have a simple HA RPi setup. I plugged in a USB SSD drive. I installed SAMBA Share. I would like to access the USB drive on the network. With SAMBA share I can only access the RPi installation drive. HA let’s me transfer the whole HA to the external drive, I don’t want that. I just want the USB as a network drive. Thanks.

I think this may be what you need.
