Excluding a Field from All Objects in a Union in Effect Schema

How can i exclude a field from all objects of a union in effect schema? I need to remove _tag from a tagged union
I tried doing

pipe(CreateIntegrationRequestSchema, Schema.encodedSchema, Schema.omit("_tag"))

pipe(CreateIntegrationRequestSchema, Schema.encodedSchema, Schema.omit("_tag"))

but it just returns a empty object
