Free shipping text translation

I want to translate the text for free shipping

https://ibb.co/X7Y2PPv

As you can see in the picture
I want to translate the text
The text inside the circle is black, I want to translate

The text inside the circle is yellow. I also want to translate the text and also put it in the middle of the box`

I used both symbols in functions.php
But they did nothing

add_filter( 'flexible_shipping_free_shipping_notice_text', 'wpdesk_flexible_shipping_free_shipping_notice_text', 10, 2 ); 
function wpdesk_flexible_shipping_free_shipping_notice_text( $notice_text, $amount ) { 
return sprintf( 'You only need %1$s more to get free shipping!', wc_price( $amount ) ); 
}

add_filter( ‘flexible_shipping_free_shipping_notice_text’, ‘wpdesk_flexible_shipping_free_shipping_notice_text’, 10, 2 ); function wpdesk_flexible_shipping_free_shipping_notice_text( $notice_text, $amount ) { return sprintf( ‘Spend %1$s more to get free shipping!’, wc_price( $amount ) ); }

Is there any help or other code other than them that translate the text and translate the word inside the box and put it in the middle of the box
