Hassio plex media server rpi4 m2 ssd usb3

I have installed home assistant on the raspberry pi 4b 4 GB
I have installed Plex media server, and linked to my account from plex.tv
I have attached USB-M2 2TB drive to rpi4 usb3 port

When I am trying to add a library to Plex, media server with the GUI, I’m not able to see my drive anywhere, because I think they have to be mounted properly to been able to access the content from the m2 drive

I want to know how to mount the device to see the content on the Plex media server

Thank you in advance
