There is a Canvas course page for a large class I'm a TA for and I want to make some content visible only to student sections I'm teaching. I saw there's an option of making the content accessible only for students with a link but wouldn't that mean that students need to click this link each time they want to access the content? Or do they only need to click the link once and then they'll be able to access the content tailored for them each time they go to the main course page on Canvas?
