Issues opening driver door

[Hook'em]

I need to address an issue with my driver's door. Opens fine from the outside. All too often, I have to put my shoulder into it to open from the inside. Pull up on the door handle and it stays up.

I'm sure I could diagnose if I pulled it apart, but I'd like to have replacement parts in hand as it's my daily driver.

Any ideas of which part or parts are broken or overly worn in this situation?
