I must be doing a simple mistake. How can I insert a link in a notification that can be opened by clicking? When I use e.g.
<a href="https://github.com/halirutan/Mathematica-IntelliJ-Plugin/issues/78">Created issue #78</a>
it is correctly rendered as link, but clicking on doesn't do anything. Other links like the ones I have in my documentation popups do work.
