Change button text

Hi,

I’ve changed the order in which fields appear on the single event page. What I would like is to add a label to the three core/buttons below so that the first one says Amazon, the second one says Hive and the third one says Waterstones. At the moment, I’m doing this manually every time I create a new event using a reusable block, but ideally would do this via the template. I can’t figure out how to set the button’s label (I’m a php n00b). Any help would be very appreciated.

add_filter( 'tribe_events_editor_default_template', function( $template ) {
  $template = [
    [ 'tribe/event-organizer' ],
    [ 'tribe/event-datetime' ],
    [ 'core/paragraph', [ 'placeholder' => __( 'Add Description...', 'the-events-calendar' ),], ],  
    [ 'core/button' ], 
    [ 'core/button' ], 
    [ 'core/button' ], 
];
return $template;
}, 11, 1 );

Thank you,

Kia
