Beginners • No IP address for headless install of Ubuntu 22.04

I am just starting with a Raspberry Pi 4B and my purpose is installing Ubuntu 22.04 server so I can then use ROS2 humble. I have been trying to flash the SD card with Raspberry Pi Imager and choose Ubuntu Server LTS 22.04.05 64-bit, then, through advanced settings configure the SSH and wireless LAN. So far so good.
However when I try to do my first boot I cannot find the IP address of my raspberry pi.

Here are a couple of tutorials i've been following:
https://roboticsbackend.com/install-ubu ... t-monitor/
https://ubuntu.com/tutorials/how-to-ins ... ntu-server

As shown in the tutorial, I find the IP address of my network:

fernando@fernando-Legion-5-15IAH7:~$ ifconfig -a

Which according to the results it is 10.0.0.229 and a mask of 24 bits.

Therefore,

But my raspberry pi is not listed? I have been trying to troubleshoot vastly by resetting the board, then, reflashing, ive also played around with the scripts such as /etc/netplan/50-cloud-init.yaml but no success and I have been trying to search through the internet for any similar issues but each one of them is very personalized so I cannot use those solutions. Can anyone please help me? I cannot access a monitor currently for a while
