How to $filter attachments list endpoint by isInli

Question

I'm developing OWA add-in using OWA REST API

I'm not able to get the filtered result when fetch the attachment list with $filter=inlinImage eq true for example:

https://outlook.office.com/api/v2.0/me/messages/{id}/attachments?$filter=IsInline%20eq%20true

or

https://graph.microsoft.com/v1.0/me/messages/{id}/attachments?$filter=IsInline%20eq%20true

knowing that is says in the resource reference that isInline is Filterable, and I got the response 200 when doing the requests above but the without filtering the data by that query params

Is this an expected behaviour? how can I get this data otherwise?
