[zikyfranky]

This is a PR for the #141 issue

[zikyfranky]

Let me know if there's any refactoring needed @PaulRBerg

Compliments of the season.

Thanks for the PR, @zikyfranky. I wanted to push some changes to your fork but it looks like you didn't give me permission to do that?

I have "Allow edits by maintainers" enabled, isn't that supposed to give you write access?

Anyways, if that's not the case, how do I grant you access without explicitly adding you as a collaborator?

I did send you an invite should that be the only route possible

[PaulRBerg]

"Allow edits by maintainers" works only for non-main branches. You made your changes directly on main.

Thanks for giving me access.

[PaulRBerg]

I'm still not able to push it to your fork, and I don't know why. Can you cherry-pick the changes from this branch, please?
