List of field field properties in blocks

Looking at Modifying blocks types and custom blocks | Kirby CMS at the section “Label” the Information says “Within the label property, you have access to an array of field properties, here are some more examples:”

Is there a full list of the available properties, or how could I best debug this, so see all the keys?

Did you find a solution?

New Link is: Custom blocks | Kirby CMS → section “Label”

Sadly no, I did not find a documented list.

No, there is no documented list, you can use most field methods that return a string.
