Catcher's Interference or Obstruction?

[TussAgee11]

MLB 6.08 (c)

A batter is entitled to 1st base when (c) If a play follows the interference, the manager of the offense may advise the plate umpire that he elects to decline the interference penalty and accept the play. Such election shall be made immediately at the end of the play. However, if the batter reaches first base on a hit, an error, a base on balls, a hit batsman, or otherwise, and all other runners advance at least one base, the play proceeds without reference to the interference. If catcher's interference is called with a play in progress the umpire will allow the play to continue because the manager may elect to take the play.

Sounds like in MLB, the manager has to alert the umpire.

I don't have my rulebooks with me, and there are no websites I can find for OBR and NFHS and LL. I'm sure if ya'll look in chapter 6 you should find something. When you do could you post it here? Thanks.
