Sure @jashpreet! Let us know if you need any help. There are other dialogs already created in the app, so you already have examples :)

@isabelcosta Please remove the available tag from this issue as it is being solved by @jashpreet. I was thinking of trying this out but then saw a PR related to the same issue.
