Load Web Page Local Flow Action
A Lightning Flow Extension
This local action will load a web page into another tab in your browser.
It takes a URL as an argument. You can pass a complete URL or construct one using flow variables and formulas.
IMPORTANT! This action will only work in Flows executing in Lightning pages. It will not work if run from Flow Setup, even if you are in Lightning Experience mode. It will not work if run in a VF page in Classic. This is due to a limitation of the underlying event. For more information, see this documentation
