Beginner level help with Podman Update

[iamtapu]

Would appreciate some help for me to figure out how I can update Podman.
Disclaimer: I have beginner level expertise in Linux environment.

Help needed in installing Podman Update.
Link: https://github.com/unifi-utilities/unifios-utilities/tree/main/podman-update
Difficulty: This page details might be targeted to a medium level Linux user. I am lost what I need to do.

Ultimate goal: My understand is, if I can update podman then I can somehow run a docker-compose file by executing command from a some other machine and make the docker-compose run in the UDM console. I am planning on running cloudflared tunnel which can be run on a docker compose. (Please correct me if my understanding is wrong)

What I have done so far:
I have a UDM device.
I am pretty sure I have completed the steps mentioned in here: https://github.com/unifi-utilities/unifios-utilities/blob/main/on-boot-script/README.md#install
My understanding is , running
curl -fsL "https://raw.githubusercontent.com/unifi-utilities/unifios-utilities/HEAD/on-boot-script/remote_install.sh" | /bin/sh
on a UDM console will install this script and will also install CNI Plugins & CNI Bridge scripts.
As per Podman Update page it mentions that (https://github.com/unifi-utilities/unifios-utilities/tree/main/podman-update#requirements)
Requirements
You have successfully set up the on boot script described here
05-install-cni-plugins.sh installed

I tried running the following command in unifi console and it shows the output.

:podman version

Version:            1.6.1
RemoteAPI Version:  1
Go Version:         go1.12.10
OS/Arch:            linux/arm64

I am lost for the next part.
Can some one kindly explain the steps as per a linux user with very basic knowledge?

Also a question: If I go wrong any where while doing this will it impact UDM router capability or may brick it?

Well, newer versions of Podman may not be compatible with your current firmware version, please look at the readme for links to current podman builds or the podman-update folder for instructions
