Test a Custom Property Type or Editor
After you link your custom property type or editor to your custom Lightning web component, deploy the component to your org and test it to see if it works.
Drag the component to the canvas in Experience Builder and look at the component property panel. Make sure that the expected property editors appear, and that the validations match what you expect based on your property type schema. Use each custom property editor to change that property’s value and verify that the component property in the canvas updates accordingly.
