Captain America using Mjolnir for the first time raises a question the MCU never really explains. Cap doesn't just lift the hammer. He immediately knows how to summon Thor's lightning and use it against Thanos, despite never having used Mjolnir before.

Worthy is loose term, Hela used to wield it so it isn’t all that special. It likely is asking those who will do anything if they have true belief in themselves.

There was no enchantment when it was in Hela's possession, Odin put the enchantment after The explanation for the worthiness sounds good but i think Tony fits that description but he couldn't lift Mjolnir

Odin never stated what it meant to be worthy. For all we know it was the same enchantment that he applied to Hela before locking her away.

Steve saw Thor use the hammer countless of times, it probably wouldn't be hard for him to guess the hammer would just follow his intent if he focused on it hard enough.
