Opening Home page as new tab with multi-account containers

Using Tabs Mix Plus, I’ve set firefox to open my custom home page ( which is just an html file on my computer ) as my new tab page. However, when I try and open a new tab in a specific container, it can only open the container tab in the default firefox new tab. Is there a way to open container tabs in my home page as opposed to the firefox default? Thanks!

I am using Firefox version 108.1, Multi-Account Containers version 8.0.9, and Tabs Mix plus version 1.0.0.pre11.
