Setting Search Box default value / on enter event

Hello,

I have two questions related to SearchBox in Bubble:

  1. I would like to set default value to the search box element (for instance: from URL).
    But it seams that it is not possible… How to use the default value for this component ?

I have checked exemplary answer here but it is not clear… (suggestion is: not to set). So if not to set then: what is this option for?

  1. How to handle enter in the workflow for SearchBox element ?
