Module development and code questions

I'm working on a custom module and one of the fields it has on its settings page is an AJAX button configured as follows:

I have created a View that exposes an API endpoint for audit logs. In this View, I configured several exposed filters such as time range and pagination.

Hi everyone,

I am developing a custom Drupal module and I need to pass data dynamically from one module to another. For example, Module A generates some user-related data, and Module B needs to use it for custom processing.

return [
'username' => $user->getAccountName(),
'roles' => $user->getRoles(),
];
}
