PHP 8.2 Fatal error

In file php/class-minute-control.php, method set_inline_excerpt()
Code:

if ( is_admin() && ! wp_doing_ajax() ) {
    return;
}

Is causing fatal error since the function is called by get_the_excerpt filter and as per documentation:

Note that the filter function must return the excerpt after it is finished processing, or page sections showing an excerpt will be blank, and other plugins also filtering the excerpt may generate errors.

method should not do void return.
