Excerpt: 3 dots to any symbol

Hello everybody
I have a question.
How to change 3 dots on excerpt title and in the post (modul) to any symbol or empty?
I want to change 3 dots to 1 or remove any symbol altogether.
Example:

What needs to be written in the file function.php or anywhere else?
I tried to apply this code in function.php, but it did not work:

function new_excerpt_more($more) {
global $post;
return '';
}
add_filter('excerpt_more', 'new_excerpt_more');

Thanks for the help 🙂

this line of code:
if (trim($excerpt) == '...' {
change the 3 dots in the excerpt post AND Title post

I found. But to change 3 dots, need to make changes to 768 line, but not to 778, as indicated on your screenshot.

And thank you for your help.
