How to switch from wifi to wired connection

I have been using my rpi 3B+ for 6+ months with WiFi and want to switch to a wired connection. When I set it up I used the my network file with the following:

[connection]
id=hassos-network
uuid=72111c67-4a5d-4d5c-925e-f8ee26efb3c3
type=802-11-wireless

[802-11-wireless]
mode=infrastructure
ssid=xxxxxxxx
# Uncomment below if your SSID is not broadcasted
#hidden=true

[802-11-wireless-security]
auth-alg=open
key-mgmt=wpa-psk
psk=xxxxxxxxxxxxxxx

[ipv4]
method=auto

[ipv6]
addr-gen-mode=stable-privacy
method=auto

What do I need to do to change it to a wired connection?
Thanks
