Modifications are lost after upgrade plugin

Hi @stantinv

Thanks for the reply.

I have made changes in button function. see below and what to do to take these on child theme or how to protect from update the plugin.

function button( $echo = true ) {
$content = apply_filters( ‘tinvwl_wishlist_button_before’, ” );
$text = ( tinv_get_option( ‘add_to_wishlist’ . ( $this->is_loop ? ‘_catalog’ : ” ), ‘show_text’ ) ) ? apply_filters( ‘tinvwl-add_to_wishlist_catalog-text’, tinv_get_option( ‘add_to_wishlist’ . ( $this->is_loop ? ‘_catalog’ : ” ), ‘text’ ) ) : ”;
$icon = tinv_get_option( ‘add_to_wishlist’ . ( $this->is_loop ? ‘_catalog’ : ” ), ‘icon’ );
$icon_color = tinv_get_option( ‘add_to_wishlist’ . ( $this->is_loop ? ‘_catalog’ : ” ), ‘icon_style’ );
$icon_class = ”;
$action = ‘addto’;
if ( empty( $text ) ) {
$icon_class = ‘ no-txt’;
} else {
$content .= ‘<div class=”tinv-wishlist-clear”></div>’;
if ( tinv_get_option( ‘general’, ‘simple_flow’ ) ) {
$text = sprintf( ‘<span class=”tinvwl_add_to_wishlist-text”>%s</span><span class=”tinvwl_remove_from_wishlist-text”>%s</span>’, $text, apply_filters( ‘tinvwl-add_to_wishlist_catalog-text_remove’, tinv_get_option( ‘add_to_wishlist’ . ( $this->is_loop ? ‘_catalog’ : ” ), ‘text_remove’ ) ) );
} else {
if(is_shop() || is_product_category()) {
$text = sprintf( ‘<span class=”tinvwl_add_to_wishlist-text”>%s</span>’, ” );
