Mosquitto-mqtt broker on RPi running?

Hello.
I’m new to Home Assistant and trying to integrate it as a visual platform for a Lora chirpstack network. I have installed mosquitto eclipse as a broker on my raspberry pi 5 and have the network up and running. I was expecting to go into home assistant and install an MQTT client but I am not completely sure here but under settings/Devices & services/Add Integration I do not see how to set up as a client or how to subscribe to the published data. Can someone explain to me a little about how to go about this?

I am new to this networking so feel free to dumb it down.
Thank you

Add integration. Choose MQTT. Choose MQTT again.
