The lint error seems to be unrelated to the changes in this PR. Please let me know otherwise 🙇

@ishaan-jaff Could you have a look at this? I'm not sure what to do about the lint failures. Thanks a ton 🙇

@ishaan-jaff @krrishdholakia Would be really awesome to have this in. It's causing quite some unnecessary load on our systems. Let me know if I can do anything to make your review easier.
