Need help with blog post permalink!

I have a wix premium site. My post URL is shown in this format:

yourdomain.com/post/blog-post-URL

I want to change the name of the sub folder ‘post’ in this URL. I have tried everything but I am unable to do it.

There isn’t even an ‘Advanced SEO Option’ in post page settings.

I would really appreciate the help!

As for changing the post part, you won’t as that is part of the Wix Blog app setup.

Examples
Get the current blog post’s information

$w('#myPostPage').getPost()
  .then( (post) => {
    let postTitle = post.title;
    let postContent = post.plainContent;
    let postImage = post.coverImage;
    // see example post object below
  } )
  .catch( (error) => {
    console.log(error);
  } );
