Need help removing the Right Inner Lining Assembly

The chamber heat circulation fan on my month old H2C failed and Bambu sent me the replacement, but despite my experience fixing printers this is a very elaborate procedure and I’m currently stuck trying to remove the Right Inner Lining Assembly - I removed all the screws mentioned and don’t see any others, but the bottom left still seems hung up on something. Has anyone got experience removing this on their H series printer and have any tips? It might even just be technique in which way to push/pull the part to remove it. The pictures on the Bambu wiki (Replace H2 Series Right Inner Lining Assembly/ Chamber Heat Unit/ Chamber Heat Circulation Fan | Bambu Lab Wiki) don’t appear to be sufficient for me, I could really use a video.

Here’s a video of where I’m at. There’s either something I’m missing that needs to be freed, or maybe I just need to know what the proper motion is to free the assembly. H2C Right Inner Lining Assembly
