Requesting GPS_STATUS message

Hello,
I have been trying to use the MAV_CMD_SET_MESSAGE_INTERVAL command to request the flightcontroller to emit the message GPS_STATUS #25, but it doesn’t work, I only get a command ack in mavlink inspector . Is there another specific way to enable this message?
I know the problem is not my code because it works when using another message not normally sent by the flightcontroller, EXTENDED_SYS_STATE, the only difference between the instances being the id of the message I am sending.
