Full use of FP3+ camera with LineageOS possible?

Hi all.
I am a new FP3+ user and I am running LineageOS 19 on it
It seems, that it is not possible to use the “+” features in this combination. The default camera app lets me set not more than 12 MP as solution for the rear camera.
Is this fact, or can this be enabled by i.e. using another app?

Let me have that very clear: I have very few (and very clear) requirements on a phone. Camera solution is one of the least important. However, I would not like the thought, not to use the full power, just because I missed something.

Best regards,
