Hello there, @Jlee29 ...
Was the shared content from a colleague at the same school? Or, was it shared by an instructor at another school? Also, do you know if the external LTI tool was installed at your school's Canvas account level? Or, was it installed in the instructor's course only? These are questions that you'll probably need get assistance from your school's local Canvas administrator or from someone in your school's Online Learning/eLearning department. If the external tool was only installed in one course, it would make sense that you could not use it in your own course. Again, speak to someone at your school to learn how this was all set up. I hope this will be of help to you. Take care, stay safe, and be well.
