Do players who don't attack the titan still get credit for the kill FOR PURPOSES OF OPENING TITAN CHESTS?

I asked this question earlier but after reviewing it and the responses (which I appreciate) I think the title was misleading. I know that non-attackers get no Titan loot. I was wondering if they get credit for the kill for purposes of the 5 kills needed for opening the titan chests.

We are looking for members in Keep America Great.

“I have a question for those of you who are more knowledgeable about the game than me. If players in my alliance do not participate in attacking the titan still get credit for the kill to be applied to opening their titan chest? I have never NOT attacked a titan so I have no way of knowing. Thank you in advance for your feedback.”

You need to deal damage to the titan to get credit towards your titan chest.

Thank you for responding Wharf.
