Upload 400 mb apk size to google?

I can’t find proper way to package android as google will not let me upload more than 100 mb file size.
I have been reading on internet about app bundle, asset delivery and DLC.
Now I am confused. I am very new to this and all i know is simple way to package for small file size.
Is there any tutorial for DLC or app bundle ?

Tink Tong ! anyone ?
