How to remove/delete file in IRCC portal?

[canadian_visa_2024]

I am working on the applications of visitor visa for my parents in IRCC portal, but I uploaded my employment letter under OPTIONAL DOCUMENTS at the end of process when I was working on the application on the first day. Now I realize that, I couldn't remove it or leave it as blank. Does anyone know how to do it?
-employment letter should be mine or my parents' ?
-how to leave it as blank since it is optional document?
Thanks
