To create a camera animation using Unity Timeline, follow these steps:
Make sure you have created an interaction.
Select the interaction object and use it's Timeline Window.
( If you can't find it, In the Unity editor, select "Window > Sequencing > Timeline" to open the Timeline window .)
Drag and drop your camera GameObject called "Camera Dummy" onto the Timeline window.
To create a keyframe for the camera's transform, click on the "Record" button in the Timeline and then move and rotate the camera as desired. This will create a keyframe at the current time in the Timeline.
To create additional keyframes, move the Timeline play head to a different point in time and repeat the process of clicking the "Record" button and adjusting the camera's transform.
To preview the camera animation, you can use the "Game" view and preview the Timeline.
