Protect Advenced Custom Fields (ACF)

Hello,

I installed pro paid subscriptions for free !!
I configured the plugin and followed the link to protect ACF content :
https://www.paidmembershipspro.com/restrict-the-display-of-advanced-custom-fields-acf-fields-by-membership-level/.

I opted for option 1 :

// Display Advanced Custom Fields for Levels 1 and 2 only.
if ( function_exists( 'get_field' ) && function_exists( 'pmpro_hasMembershipLevel' ) ) {
	if( pmpro_hasMembershipLevel( array('1', '2' ) ) ) {
		if ( get_field( 'test_field_1' ) ) {
			the_field( 'test_field_1' );
		}

		if ( get_field( 'test_field_2' ) ) {
			the_field( 'test_field_2' );
		}
	}
}

The content of my album page is well protected.
Except that I have no link on the page to redirect the user to the page of paid subscription levels Pro.

What must be added to be able to have a sentence and a link like: “You do not have access to the content.
You must register by clicking on the following link: XXXXXX “??

Thank you for your help !!
Nico
