Button Placement in Zoom

I’m developing a Zoom App that sends messages containing sections with buttons. I have two questions regarding button behavior and layout:

  1. Can a button in a Zoom App message be of type “Open URL” (i.e., open a specific link when clicked)?

  2. Is there any way to adjust the spacing or placement of buttons within a section? Currently, the buttons appear aligned to the extremes of the section, and I’d like to control their positioning.
