The current behavior is as follows:
First, I duplicated the Bow (Item Definition) from the Demo and created a new Bow_MyTest (Item Definition).
Then I created my own bow and assigned it to Bow_MyTest.
As a result, when I press the left mouse button in the game, my bow cannot shoot arrows.
To continue troubleshooting, I changed the definition of the original Demo bow prefab, which was working correctly before, to Bow_MyTest. As a result, that Demo bow also could not shoot.
However, if I do not use Bow_MyTest and instead keep using the original Bow (Item Definition), then map the Bow prefab to my own bow model/prefab, everything works correctly and the bow can shoot normally with the left mouse button.
