How to define default for a variable that has no value in a text card?

Hey there.

I was reading the documentation here: Fun with Markdown in your dashboards and you mention the following:

If no value is plugged into the filter, Metabase will render the unsightly {{PLAN}} variable. To handle cases where the filter has no value, you can set a default value or, better, hide the text by surrounding the variable text with double brackets to make the text optional.

However, there's no code showing how to set up a default. Only to make it optional.

Can you showcase how to do that?


Which version are you running?

Hey Luis, I'm running v0.50.0.
