Hey @RHo, actually the latest iteration already displayed the message on top of the mentor's username. The message was then auto-dismissed only when the user did ask a question to their mentor. See animation below (taken from T223135#5372483)

I have also iterated the design to show a dismissible message, so that the user is more likely to read it (a downside of the previous solution could be that the user would click on CTA before actually reading the intro message):

The dismiss action could be animated as per mockup below:

This ticket is ready for development implementing the mentor introduction message as a dismissible tooltip within the mentor module as per @Cntlsn's last mocks (version A) and interaction.

I do have updated visual styling of that message (border, bgcolor, padding) that would be a part of style updates to all modules on the newcomer homepage though, as per T232546. So we can discuss whether to hold off until the T232546 so styling is changed once only.

Thanks, @RHo. I am moving this back to "Upcoming Work", since it's not strictly necessary for newcomer tasks.
