Hi @mgregor,
I will ask two questions before I respond.
- Has your institution disabled (which is different than either it being hidden by default or not visible) the native "Syllabus" link from your course(s)?
- Has your institution disabled (which is different than either it being hidden by default or not visible) the "Course Summary" feature?
If the answers to those two questions are "no", then there are two (series of) steps.
If "Syllabus" has not been disabled, follow the steps at How do I manage Course Navigation links? - Instructure Community - 1020 .
If "Course Summary" has not been disabled, follow the steps at How do I use the Syllabus as an instructor? - Instructure Community - 638 .
If your institution has disabled those two, it would need to be custom designed as a workaround and I am not sure anyone would be able to help with that.
