Filter a Reference to show Documents that Contain the Current document's Title in One of the referenced Document's Array Objects

I'm currently trying to filter a reference to only show documents that contain the current document's title in one of the referenced document's array objects. So, the `artist document`'s

project

reference object should only show an array of

project

documents where that

artist

has been referenced in the project document's

creditList

(which is an array of references to all artists). This works :
But ideally I can loop through all credits :

credits[]->{title}

and see if any titles match the

document.title

. Is this possible? If so, any tips as to how I might go about doing this?

$artist in credits[]->title

worked🙂
