Capturing camera movement using mouse and keyboard

Hi. I´m using UE 5.03 and I want to freely move the camera using navigation keys and the mouse and capture this movement. I´m trying to do this using Take Recorder. I created a keyframe for the camera to fix its start position. In some cases, when I hit the Rec button, the camera starts in another place. Another issue is when the animation is recorded inside an existing Level Sequence, nothing happens…
What´s the correct workflow to capture this kind of camera moving? It´s been hard to find a good solution and tutorials about this specific case.
Thanks in advance.
