How do I find my Form again

DingkunXie In my case, it's https://www.microsoft365.com/ (http://www.office.com wants me to log in again, so I don't think it's the right way for my university account). Anway "by design" is a strange thing for me. A good design means it's easy to use. Going to m365 and searching for my "filled forms" (even by their name) won't show anything. The advanced search allows me to tick boxes for  Powerpoint, Word, Excel etc. files, but "filled forms" is not one. 

I have to go to "forms.office.com" to find them. So, I'd say Forms aren't yet fully integrated into the M365 cloud if you can't find them at the top level. "By design" means to me there's some other reasons (internal to Microsoft?).

Thanks again for helping.
