+1. Initialize a mock `StreamVideo` with the following method: `StreamPreviewDataUtils.initializeStreamVideo`.
 2. Wrap your composable with the `VideoTheme`.
 3. Use the provided mock instances for Stream Video UI components.
 
 This library provides the following mocks:
 
-- **mockCall**: Mock a `Call` that contains few of mock users.
-- **mockParticipant**: Mock a `ParticipantState` instance.
-- **mockParticipantList**: Mock a list of `ParticipantState` instances.
-- **mockUsers**: Mock a list of `User` instances.
-- **mockVideoMediaTrack**: Mock a new `MediaTrack` instance.
+- **previewCall**: Mock a `Call` that contains few of mock users.
+- **previewParticipant**: Mock a `ParticipantState` instance.
+- **previewParticipantsList**: Mock a list of `ParticipantState` instances.
+- **previewUsers**: Mock a list of `User` instances.
+- **previewVideoMediaTrack**: Mock a new `MediaTrack` instance.
 
 For example, you can build a preview Composable for `ParticipantVideo` as in the example below:
 
 ```kotlin
 @Preview
 @Composable
 private fun ParticipantVideoPreview() {
-    StreamMockUtils.initializeStreamVideo(LocalContext.current)
+    StreamPreviewDataUtils.initializeStreamVideo(LocalContext.current)
     VideoTheme {

+            call = previewCall,
+            participant = previewParticipant,
         )
     }
