MUI for Figma Free version, most components not appearing under assets

Hi everyone,

I’m pretty new to setting up design systems in my files, I’m trying to use the material design system for a new file, I have published a copy of it however only a few of the components are showing up in the assets bar.

These are the only components that are appearing:

• Date picke
• alert
• avatar
• button
• card
• checkbox
• text field

Am I missing something? Why are some components set up as components in the file and the rest as instances? How do I access the instances in the assets bar?

Thanks in advance for everyones help!!
