How to update Idle Animation

No this post is not for changing default idle animation

I constantly change the Idle Animation inside my game, but it won’t update until the player moves again.

What I want to achieve:
IdleAnimation1 → UnequipTool → IdleAnimation2

What is currently happening:
IdleAnimation1 → UnequipTool → Player Walks → IdleAnimation2

How do I update the idle animation without having the Player move?
