Hi @analyticalminds ...
The image I shared with you earlier is from a different Canvas environment where I have administrator access. So, since you are using a FFT account, you would not have access to that screen that I shared. This is the Guide for Canvas administrators:
How do I change the sender name in account email n... - Instructure Community (canvaslms.com)
Again, keep in mind that if a Canvas admin chooses to use the second option to use a custom name, it most likely would not be the name of an actual person...but rather the name of the school. This is because when course invitations are sent, it would display the school name instead of your name. You wouldn't want your name here since these invites apply to all courses/instructors at your school...not just your courses.
I'm guessing this is where you may have seen this in your own example...unless they somehow figured out something different than what I've described above.
Hope this helps.
