Attacking with a Thrown Monk Weapon

I'm just about to play my first game of 2024/5.5 and I'm not quite sure how a couple of rules interact

"Thrown
If a weapon has the Thrown property, you can throw the weapon to make a ranged attack, and you can draw that weapon as part of the attack. If the weapon is a Melee weapon, use the same ability modifier for the attack and damage rolls that you use for a melee attack with that weapon."

So the typical person would use str to attack and damage when they throw a hand-axe, ok

But how does that interact with the Monk's Dextrous Attacks?
"Dexterous Attacks. You can use your Dexterity modifier instead of your Strength modifier for the attack and damage rolls of your Unarmed Strikes and Monk weapons."

If a Monk throws a spear (which is a simple weapon so they attack and damage with dex in melee) do they still use dex if they throw it?

Yes.

As stated in the rule you quoted, when you throw a melee weapon, you use the same ability you'd use when making a melee attack with it. Monks would use Dexterity when making a melee attack with a spear, so they also use Dexterity when throwing it.

This works exactly the same in both 5e and 5.5e.
