There are only a few open source camera apps and they cannot use all the features of a Pixel 7 camera. In general, the higher the quality of the stock Android camera app, the more features you will have to do without.
It is easy for you to link the apps you use from the Play Store. I first have to search around and, as with ING for example, note that there are country-specific variants. Please also put some effort into your question.
