[Gelöst] Make Custom Options Page translateable

I am currently trying to translate a website which I created a custom options page for.
The option page is created by the following code

add_menu_page('Website Optionen', 'Optionen', 'administrator', __FILE__, 'custom_option_page' , plugins_url('https://cdn.wpml.org/images/icon.png', __FILE__) );
add_action( 'admin_init', 'register_websites_settings' );

function register_websites_settings() {
register_setting( 'website-settings-group', 'phone' );
register_setting( 'website-settings-group', 'e-mail' );
...
}

<form method="post" action="options.php">
<?php settings_fields( 'website-settings-group' ); ?>
<?php do_settings_sections( 'website-settings-group' ); ?>
<table class="form-table">
<tr valign="top">
<th scope="row">Telefon</th>
<td><input type="text" name="phone" style="width: 100%; max-width: 360px;" value="<?php echo esc_attr( get_option('phone') ); ?>" /></td>
</tr>

<tr valign="top">
<th scope="row">E-Mail</th>
<td><input type="email" name="e-mail" style="width: 100%; max-width: 360px;" value="<?php echo esc_attr( get_option('e-mail') ); ?>" /></td>
</tr>
.....

How can I make the values for the options translateable?
