API: Add endpoint which returns the current match (sendouq OR tournament) of a user

[strohitv]

I wanna craft a little overlay for myself which I can use to show my current match on stream.
SendouQ is possible but there's currently no real way to get the current tournament match of a player.

Could you add an endpoint GET /api/user/{userId}/active-match which lists either the id of the current sendouq or tournament match?

The response could be similar to the GET /api/sendouq/active-match/{userId} endpoint just with a flag added to distinguish between sendouq and tournament:

export interface GetUsersActiveMatchResponse {
    /** The user's current match ID or null if none */
    matchId: number | null;
    /** a flag which tells what kind of match the user is in right now */
    lobby: "sendouq" | "tournament" | null;

    // alternative option instead of lobby, dunno which one would be better.
    // Would be null for sendouq or no match and the id of the tournament for tournaments
    tournamentId: number | null;
}

I think both lobby and tournamentId as fields would have their upsides, so maybe adding both would be beneficial if it doesn't come with too high cost.
