Auto starting NPM program after reboot

Hey all, Forgive me am still fairly new to coding/software, recently got my hands on my Pi 5 which I'm loving, following the guide found here - https://github.com/vexorian/dizquetv/wiki/Raspberry-guide I've set up and have dizquetv working on my pi, the only issue is when the device powers off I need to SSH in, start a screen session and restart it with an NPM Start command. Is there a way to automate this, and could someone help me out with some idiot-proof steps? Thanks in advance 🙂
