2 Extreme 200 series switches, looking to trunk with multicast

[SuperAkuma]

Scope of project:

I have 2 Extreme 220-12P-10GE2 switches that I'm attempting to use interface port 13 to trunk together using 30M CAT SFP+ adapters. Multicast needs to be available for VLAN 10 (being used for AVoIP hardware), and also allow for traffic on native VLAN 1. I would need to allow for specific ports to communicate between these 2 VLANs, while restricting the multicast traffic to only VLAN 10. Is this even possible, or am I chasing a "ghost" due to my limited networking skill set? Any constructive input is appreciated

I can verify the data flowing between the two switches, but only for native VLAN 1 it appears. DHCP flows through the switches too, as the server lives upstream from the primary Extreme 220

For reference, these are the SFP+ adapters I've installed: https://www.amazon.com/dp/B08NW1VBX6?psc=1&ref=ppx_yo2ov_dt_b_product_details
