i noticed you flipped some single-tick quotes to double. do you have that linting captured in your pipeline and local dev setups? it would suck to have to deal with those flipping bakc-and-forth if different devs are handling them differently.

Yes you are right. That formatting is because of the prettify extension that I use in my local vscode. I will add a config file to ensure same linting and formatting rules applies to everyone. I am merging this and creating a new issue for this.
