AppBlock installed without asking?

We have a FP3 running with IMG-e-1.2-r-20220727206630-dev-FP3
and netguard pro (most inportant)
Today there was an update for AppBlock offered in the appstore.
Any idea how that got onto the divice without deliberatly installing? :thinking:
I’m quite shure it wasn’t preinstalled - should have noticed that when I configured netguard
