If you just want to show shortened testimonials, use char_limit in the shortcode.

Please check the parameters here: https://github.com/axelerant/testimonials-widget/blob/ed774f7bb8da9ae038101e0b58e1695e0eebd9cb/includes/class-testimonials-widget.php#L760

Let me know if you need anything else.

Thanks
