Accessing Card parameter in Shortcut

What action do I use in a Shortcut to access the input parameter that the card passes to the Shortcut? I want a series of cards to call the same Shortcut but each with different parameters.

It would appear that I must turn on Share sheet for the Shortcut so that Shortcut Input shows up as a variable. Is that the right way to do this? If so, I did not see this in the MFCDeck docs.

To use the input parameter in Shortcuts, you must enable the share sheet option to access the input variable. That’s a standard Shortcuts feature.
