Hello @AineFusciardi
I understand that you are having trouble locating a get started page to view a lecture recording.
Without being able to take a look at your course as an example, it might be hard for us here in the Community to point you in the right direction.
However, you might be able to locate this specific page in the course you are taking. Sometimes specific pages will be located/shared under the modules page in the course. Does your course have a button labels as Modules in the course navigation to the left?
You can also check the home page and see if they have a get started link there.
