The button to open the door on my LG Microwave is not working well

I have a LG counter top microwave (model LMC2075ST) that is only about a year and a half old, and the button to open the door is not working well. You should only need to push the corner but now you have to push the whole thing and it’s difficult to do. The warranty ended 6 months ago. I’m sure taking to a repair shop will cost $100 or so, doesn’t really seem worth the cost to repair. (Exactly what the manufacturers want!)

I’m wondering if anyone has any experience fixing this. LG lists parts on their website, but it’s not clear if the one that says Button assemble is this button or not.
