Note

Do we really need the $button variable?
https://github.com/joomla/joomla-cms/blob/4.0-dev/administrator/components/com_users/tmpl/debuggroup/default.php#L62-L85

						<?php foreach ($this->actions as $action) : ?>
								<?php
								$name  = $action[0];
								$check = $item->checks[$name];
								if ($check === true) :
									$class  = 'text-success fas fa-check';
									$button = 'btn-success';
									$text   = Text::_('COM_USERS_DEBUG_EXPLICIT_ALLOW');
								elseif ($check === false) :
									$class  = 'text-danger fas fa-times';
									$button = 'btn-danger';
									$text   = Text::_('COM_USERS_DEBUG_EXPLICIT_DENY');
								elseif ($check === null) :
									$class  = 'text-danger fas fa-minus-circle';
									$button = 'btn-warning';
									$text   = Text::_('COM_USERS_DEBUG_IMPLICIT_DENY');
								else :
									$class  = '';
									$button = '';
									$text   = '';
								endif;
								?>
							<td class="text-center">
