Hi Pavel, I was afk for the last two days. As the deadline is already here. I have submitted the proposal after reviewing your comments from the mail. Thank you for taking the time out. Thanks to Noor Aman and Gedare, I have gone through the comments and have incorporated your suggestions in the proposal. Will continue in discord group.
