Why are my keyframes not showing up in timeline?

I’m trying to loop some keyframes with a cycles modifier. But the keyframes don’t show up in the timeline. Even though I have the object selected that they belong to. They DO show up if I uncheck “View-Only Keyframes from selected channels,” and it shows ALL the keyframes for the entire project. But I’m unable to loop them with the cycles modifier. I don’t know why they’re not showing up! Take a look:

The channel that’s hidden is called “Orange Open”. But, as I said, when I uncheck “view-only keyframes” it appears. I’ve highlighted it in the second phont.

Any help at all would be greatly appreciated! thank you in advance

Hello maybe share your file (delete all the useless objects)?

Sure! Thank you so much. Here’s the Blend file.

You need to select both the node that you’ve keyframed and the object that has the material:

wow! Dude, thank you so much! really appreciate it
