@nandini45 @keshakaneria Can you please review this PR. Thanks 🙂

@Rahulm2310 Can we keep 3 in a row? Currently there seems a lot of space on right and a bit on left side of card. What do you say @nandini45?
Otherwise the modal looks perfect 👍.

@keshakaneria Yes it can be but do we need to discuss it with the design team first?

Yes, tagging @nandini45 again as a part of designing project to let us know if this can be done.

@Rahulm2310 could you fix the merge conflicts? I really like what you did here. Would love to get this on track again!
