This is the code I use to get all apps inside a project -

const stream = client.readRelationships(v1.ReadRelationshipsRequest.create({

        relationshipFilter: v1.RelationshipFilter.create({
            resourceType: 'coplanedev/app',
            optionalSubjectFilter: v1.SubjectFilter.create({
                optionalSubjectId: 'projectId',
                subjectType: 'coplanedev/project',
           

            })
        })
    }))

What should I change in this to make it work?
