Can we display region label from Layouts? We have a MYTHEME.layouts.yml file which defines regions...

layout
  label: 'Layout Name'
  path: templates/panels
  template: layout-template
  default_region: theregion
  regions:
    theregion:
      label: 'This is The Region'


In the template we display fields added to the region with

{{ content.theregion }}


Can we display the label that we defined?
The labels are for administration purposes and should not be used in templates as they are hard coded and can't be changed in the UI. A better option would likely be to use a Text field where you want to display the label as that can easily be changed.

That said, you can output the region name in the twig template like this:

{{ layout.regions.theregion.label }}
