Need help with the way a tweet is constructed thhrough a tweet share button.

I am looking to change the way a tweet is constructed using a share button on my website. I have tried to change it but either breaks the page or the tweet is missing parts. The tweet is currently constructed like this:

 

Ralf Little Destroys Jeremy Hunts Lies On The Andrew Marr Show via @username https://******.com/ralf-little-destroys-jeremy-hunts-lies-andrew-marr-show/

 

However, I would like it to be like this with the via @username being presented at the end of the tweet: 

 

Ralf Little Destroys Jeremy Hunts Lies On The Andrew Marr Show https://******.com/ralf-little-destroys-jeremy-hunts-lies-andrew-marr-show/ via @username

 

 

The PHP code below is how the tweet is being contructed:

'twitter' => array(
'url' => 'https://twitter.com/intent/tweet?text='. $post_title . $share_twitter_username .'&url='. $post_link,
'text' => esc_html__( 'Twitter', 'jannah' ),
),

This is the code for the $share_twitter_username part which is the part I would like moving to the end:

$share_twitter_username = jannah_get_option( 'share_twitter_username' ) ? ' via %40'.jannah_get_option( 'share_twitter_username' ) : '';

As mentioned, I've not been able to do it as it either breaks the whole page or parts of the tweet are missing.
