Windwalker Echo ik arms

I have been creating key frame animations with the Windwalker Echo character. This character was created by the UE crew. Does anyone know how to switch the arm ctrls from fk to ik and back again in the sequencer? The ctrl rig nodes show a ik setup for the arms but I am not able to switch them on/off so I can use that feature in the sequencer. Thanks.

I found the answer more than a week ago.
It is odd that no one ever responds in this forum.
Not even a sarcastic response.
