OData query filter by enum

Hi community, I have published an entity as an Odata Service. Now I am testing the endpoints. I have problems filtering by enums. I am not sure about the spelling of the query. Currently I use, as I understood it in the documentation /requests?$filter=Status eq Core.ENUM_Status'Required' The attribute is called 'Status'The value I want to filter by is 'Required'The enum is called ENUM_StatusThe enum is in the module core Thanks for helping.
