The Library must be Desugared. Just adding them is not enough here. Maybe Jetifying it can work (you need to try).
Jetify:

AndroidX SDK

Android Support Library was implemented and maintained in the last 8 years by Google. It includes a wide range of features and it hides many of the differences between the various Android versions. Android Support Library was replaced by AndroidX SDK. It is no longer maintained and new versions...

Desugar:

desugar - fix the "invokedynamic requires" error

Some of the new Android libraries use Java 8 features. Android doesn't natively support those features so they must be removed (desugared) at some point. When you wrap a library that includes such features you need to desugar the wrapped library. This is done with an Android tool named desugar...

You need to write a wrapper for this AAR to use which requires some java-knowledge.
Alternatively you can use JAvaObject to work with it. requires some java-knowledge too.

this may go beyond desugaring. i desugared the .aar and tried to compile the example. none of the errors you reported appeared, BUT a missing resolution of androidx fragment was triggered. when i downloaded that from maven and rebuilt, all the errors you reported came back. some googling indicated that the errors have to do with proguard. when i checked the androidx fragment .aar, it had, in fact, been built with proguard. (your .aar did not use proguard). i don't know what you end up with if you desugar such an .aar. i think this is getting above my pay grade, so i humbly abandon ship at this point. sorry.
