That would be a 9-2-1-b-4 foul, and is treated as a dead-ball. The penalty is 15 yards from the succeeding spot (including the spot of the try), at the succeeding kickoff, or at the succeeding spot in an Extra Period.
As Zap implied, if the action is well away from the action, doesn’t affect play action, doesn’t interfere with officials, and is virtually unnoticeable, maybe just use a “talk to.”
