Drupal 8.x

Hoping someone might be able to help me out. I have a custom Drupal 8 module which has a webform composite element with some settings/properties that are fields where I can either enter a webtoken to capture some data from the form or simply enter some data for later retrieving on the webform handler side. The issue is that I thought this data would be included in $_POST but it's not so I'm trying figure out how I can retrieve the data after the form is submitted. FYI, I don't even see this data being stored in the "webform_submission_data" table so not sure where it's being saved.

The question is simple, I have a Drupal 9 website with the Geolocation Field module. I use the Olivero theme.

In this theme, there is a "Hero (full width)" region. I want to display a View page with the nodes that have a geolocation field and I want to display the map in the "Hero (full width)" region.

The page and the map must share the exposed filters.

So my question is how to display the map in a different region by inheriting the exposed filters from the page?

It would be so much classier to have a full-width caret in Olivero.

Hello,
for testing purposes, I create a new Drupal 8 installation using 

composer create-project drupal-composer/drupal-project:8.x-dev drupal --no-interaction

then I immediately upgraded it to 9 using

composer update "drupal/core-*" --with-all-dependencies

but I get a list of errors like

I'm currently trying to disable a page from appearing in the search results. Does anyone know the best way to go about doing this?
