Hey @elprofejimenez - in addition to what @chriscas mentioned above, you should be able to add apps and menu items via your course settings. If you go to Settings > Apps you should be able to see the menu of external apps. You can then search up ReDirect tool, and click add, and just enter the URL and name you want it to have and redirect to, and you just have to check off the Course Navigation option so it appears on your course's side-navigation.
And you're right, us Community Coaches do not have the power to make decisions like those, however we're always willing to help to make the best out of a frustrating situation.
Please feel free to reach out with any additional questions or concerns! I hope this helps reduce some frustration.
All the Best,
Noah B.
