The script you provided should work for embedding the iframe with a width of 100%. If it’s not displaying correctly, consider the following:

Parent Container: Ensure the parent container of the iframe is also set to 100% width.
CSS Conflicts: Check for any CSS rules that might be overriding the iframe’s width.
Responsive Design: If the page is responsive, ensure that media queries or other responsive design elements aren’t affecting the iframe’s width.
Inspect Element: Use browser developer tools to inspect the iframe and its parent elements to identify any constraints.
