[RPG] How does Channel Smite work

pathfinder-2e

At level 4, Berric the cleric takes Channel Smite. He then attacks someone, expending a Harm spell. From the text:

Make a melee Strike and add the spell’s damage to the Strike’s damage.

Does this mean that the basic Fortitude save mentioned in the text for Harm simply isn't used? If Berric used a first level spell slot, which of the two possibilities below is the case when he strikes and hits?

  1. He strikes, dealing his normal weapon damage and then simply adding another 1d8.
  2. He strikes, dealing his normal weapon damage. The enemy takes 1d8 damage, but rolls a basic Fortitude save: it takes none of that 1d8 damage on a critical success, half damage on a success, full damage on a failure and double damage on a critical failure.

I think it's the first, because the text for Channel Smite doesn't mention any saving throw, but I'd just like to confirm…

Looks like option 1. Channel Smite doesn't say anything about a save, simply add the expended spell's damage to your melee strike. To be fair, it's a two-action attack that also costs a spell, and you lose your chance for the target to critically fail the save, so it's not "unbalanced", just adds some reliability (and fitting flavor) to divine melee combat.
