Help IDing shower drain type

[Star46]

Noticed a water leak coming from our second floor bathroom and I’ve got it narrowed down to the shower floor drain. I’ve got access to the drain and P-trap from the floor below but I’m having some trouble identifying the drain type with the glue that the plumber used to install the drain cover. 5 year old house. Any help is appreciated!

This is frequently referred to as a No-Caulk drain. The best replacement IMO is the Sioux Chief Jackrabbit.
