Camera interpolation between Level Sequences & Get active Level Sequence

Hi Wonderful People,

How to interpolate the cameras thru key press between different level sequences while one of the sequence is playing.

How to “get” the currently playing level sequence?, I atleast want to stop and clear the currently playing level sequence.
I tried to add nodes from this doc: Playback | Unreal Engine Documentation
But couldn’t do so inside the level sequencer, is that doc defunct or am I doing anything wrong?
