Herald of Orange Light vs BLS Envoy

Am I right in thinking that Herald of Orange Light can negate the double attack effect of Black Luster Soldier - Envoy of the Beginning before it attacks for the second time in a row and destroy the card? I think it's possible but I want to make sure. Thanks.

His second attack is a trigger effect that activates in the damage step.

Herald of orange light works in the damage step.

When the opponent calls his intent to attack a second time, Herald of Orange Light can be activated to destroy BLS-Envoy.
