Update a flow variable

[bimcdona]

I want to update a flow variable from the evaluate node.  My Javascript is below but does not work:

let $(n2.inboundWebhook.msisdn) = $(n2.inboundWebhook.msisdn).replace("+", "");

So it appears that you cant modify node data via the evaluate node but you can modify custom data, but not directly in the evaluate node.  You have to update it via the Transition-Action -> On-Leave using the evaluate output to set the custom variable.
