Hi @Bestla,
You'll likely need to speak to your school/institution Canvas team (usually in the eLearning / IT / Digital Education areas) about this to get a solid answer. My first guess is that your school configured the Echo360 course navigation tool to only be visible to teachers/admins, but I could be completely wrong about that. Unfortunately, members of the Instructure Community don't have aby access to your exact Canvas environment to be able to verify something like that, so your local team will be much better equipped to answer a question like this about your specific Canvas instance.
Please let us know what you're able to find!
