Bell notification on a tab for messaging

Hi, I have a ‘Message Board’ tab under which we interact with different stake holders. It’s a message board. Requirement: When there is any new message is received for any user who logs in, then a bell icon is placed on the ‘Message Board’ tab(like notification on Facebook on message tab). It’s a notification for the user that there are new messages for you since your last log out. Not Email push notification. Can someone suggest a way to put the bell icon on the ‘Message Board’ tab which is configured in navigation? Any inputs from anyone? Thanks in advance!

Add a dataview with datasource a microflow which retrieves the first of all the user’s message having a create date > the user’s last login. In that dataview, add a picture.
