Hi LUFREDDY77,
There are two standard ways to get this out:
The first is via the “aec” file (after-effects-composition), which you can find in the Save part of the Render Settings.
Or you use Capuccino to “bake” the camera and disable the Camera Tag while saving it as a Cineware file.
Both open in After Effects, and the extracted camera has the keyframes.
Since I try to not answer (ever) from memory, as things might change, here are the files:

The 01 is the AEC based workflow, and the file with the 11 in it the Cineware based workflow.
If you prefer one or the other and related questions, please let me know, I will look into it.
All the best
