How to generate union type from GRPC to graphql

[ntodorovdespark]

Hello there,

I am trying to generate a grapqhl union type. I have the following GRPC schema that should be translated to Graphql from Graphql Mesh:

message Event {
oneof event {
AEvent aEvent = 1;
BEvent bEvent = 2;
}
}

The result is:

export type Event = {
__typename?: 'Event';
aEvent?: Maybe;
bEvent?: Maybe;
};

I want to have the following as a result:

export type Event = AEvent | BEvent
