You might get it to work by manually copying those file types into the proper folder. It might be worth trying different folders under
/Library/Containers/Kindle/Data/Library and seeing if the app detects their presence up when restarted.

If by "things" you mean books then I strongly doubt that. My understanding is that the upgrade process is simply copying collections from the old app to cloud storage shared by all of the Kindle apps under your account. The new app is independent of the old one and uses different DRM keys so book files can't just be copied over.

In addition KFX format has different variants depending on the platform to which it is sent. The new app will likely get a different set of files than the old one, likely the same files that are delivered to iOS devices.

There are two components (DSN and account secret) established when the app is registered and used as part of the key for DRM. Without a way to discover those the Kindle for Mac app is going from being one of the more insecure Kindle apps in terms of DRM to being completely unbreakable.

In the old app this data is stored encrypted in a file named .kinf2018 found in either /Library/Containers/com.amazon.Kindle/Data/Library/Application Support/Kindle/storage or
/Library/Application Support/Kindle/storage. I assume that the new app takes advantage of more secure storage options now available in MacOS.

The Kindle for PC app is going the same way, however it is going to take longer to happen there. Windows 11 includes built in Android emulation with apps supplied by Amazon, including the Kindle app. Users can use both the old Kindle for PC and this new app and they are independent of each other. I suspect that once Windows 10 reaches end-of-life in two years there will be a similar deprecation and transition to the new app on Windows.
