Show taxonomy fields on single posts

Resolved schoefl

With the help of https://www.advancedcustomfields.com/resources/adding-fields-taxonomy-term/ I added some fields to the WP taxonomy ‘post_tag’. With a shortcode according to the following pattern, I display the fields in the sidebar.
```
function short_func()  {
 $term = get_queried_object();
...
 if( get_field('autor') ) {
  $output .= "<h2>".get_field('autor', $term)."</h2>";
  }
...
 return $output;
 }
add_shortcode('autor', 'short_func' );
```
This works wonderfully on the archive page (tag.php), but not on the single posts (single.php). I read that I had to add something like $post_id or $term_id to the selector. But I am not competent enough to turn the theoretical description into a working script line.

Please, how can I also display the values of the tag fields on the single posts with the corresponding keywords?

The problem is solved. I found a YouTube video where I was able to understand step by step what is exactly part of the code on https://www.advancedcustomfields.com/resources/adding-fields-taxonomy-term/ and what is just a placeholder that I have to replace with individual values.

For everyone with similar problems:


// Shortcode for sidebar
function short_func() {
 $output = '';
 if( is_single() ) {               // single posts
  $post_tags = get_the_tags();
  $term_id = $post_tags[0]->term_id;
  }
 else {                            // tag archive
  $queried_object = get_queried_object(); 
  $taxonomy = $queried_object->post_tag;
  $term_id = $queried_object->term_id;  
  }
 if( get_field('autor', 'post_tag_'.$term_id) ) {
  $output .= "<h2 class='widget-title'>".get_field('autor', 'post_tag_'.$term_id)."</h2>";
  }
 return $output;
 }
add_shortcode('shortcode-name', 'short_func' );
