The two .ZIP-files only have something to do with TWRP insofar as they can be installed with TWRP.
As I wrote above:
I did not use these two files because they were not necessary for the /e/OS ‘Q’ to work. A clean Stock Android 10 as a base and the /e/OS ROM ‘Q’ are a good team to use the S9 99.99% deGoogled.
