Please follow the below steps to add a button on your custom page.

1) Review this block and do the required changes in your custom module file.

/var/www/html/magento2/vendor/magento/module-checkout/Block/QuoteShortcutButtons.php

2) Add this code in your custom page block file (php)

    /**
     * Dispatch shortcuts container event
     * @return $this
     */
    protected function _beforeToHtml()
    {
        $this->_eventManager->dispatch(
            'shortcut_buttons_container',
            [
                'container' => $this,
                'is_catalog_product' => $this->_isCatalogProduct,
                'or_position' => $this->_orPosition
            ]
        );
        return $this;
    }

I have not checked in detail but logic is the "shortcut_buttons_container" event configured this button and it will render on particular page section.

Hope this will help you.
