How to get all the links in customer my account?

create a custom block and write the following code,

Vendor\Module_name\Model\Config\Source\Sections

    <?php
            namespace Vendor\Module_name\Model\Config\Source;

            use Magento\Framework\App\Utility\Files;

                protected $utilityFiles;

                protected $links;

                protected $list = [];

                public function __construct(
                    Files $utilityFiles,
                    Links $links

                /**

                }

                /**

                        'value' => (string) $rb->block['name'],
                        'label' => (string) $rb->xpath('block/arguments/argument[@name="label"]')[0],

                    ];
                }
            }

then call the blocks on your template file

  <?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$customerLinks = $objectManager->get("Vendor\Module_name\Model\Config\Source\Sections")->toOptionArray();

echo "<pre>";print_r($customerLinks);
exit;

?>
