Reaction System Guidelines -> Environmental -> Aerobic -> Enable/check "Direct Photolysis (ranked)" and "Envipath microbial biotransformation" (may not be able to the latter with other libraries).
So start by just adding ranked photolysis with abiotic hydrolysis when selecting the above path.
For gentrans inputs logic:

More gentrans input logic to come.
