When adding an LTI external tool using XML (according the documentation here: https://canvas.instructure.com/doc/api/file.tools_xml.html), you have the option of adding an placement at "User Navigation" level:
<lticm:property name="text">Tool Name</lticm:property>
When checking the user navigation (click on "Account" picture/avatar), you get to see a list of links, without seeing the added external LTI tool:
But once you click on any of those items (for instance “Profile”), you finally do get to see that External LTI tool (see MyTime Table):
This is quite hidden & unlogic for students, as they need to click first through the "first" user navigation list, in order to reach the "second" user navigation list.
Can External LTI Tools, when added to the "User Navigation", also be added at the "first" User Navigation list?
