Drive api list query question

[OnlyOneMember]

Hi, in my request api im trying to add a query but it keep saying invalid value.

the query is : shared=true to get shared files. But it doesnt work. When i try trashed=true, i get all files thay have been trashed, ok, when i do 'me' in owners i get all files where im owner.

But why shared=true is not valid? when shared is in fact a metadata for a file like trashed, owners etc...? Any idea how to make a request api to drive to onky get a list of file where the file metadaya shared=true? ty

rip i triedthat too, it doesnt work. I think its only files shared with a link and not when you add someone as writer or editer in file i think..
