Failed to publish branch to remote Github repository

Question

I am using Github desktop as an interface and I am trying to push an initialized repository onto GitHub. I actually created the repo on GitHub and cloned it into my local machine and thus is where i made changes.

however even after my changes; I cannot push the changes I have committed towards the remote GitHub repo.

Error message displayed by Github desktop

I have tried using the command git push -u origin main to push changes through the terminal and it still gives me an error displayed below.

I need help to see what I am missing; pointers are welcome.
