Tamara is not working

Hi, I’ve installed this plugin to the website https://taibastaging.com/2196-podacademy and followed this guide to https://docs.tamara.co/platforms/woocommerce/wc-widget/ to finish the integration. I’m frustrated to mention that this payment gateway is not working and unable to see tamara payment option on checkout page. You can test on your own here https://taibastaging.com/2196-podacademy. Can you please check and guide me? Also, I want my payment method integrated as this live website has: https://pod-academy.com/cart/checkout/express/course/1172

Looking forward to hear from you soon.
Thank you, Ashraf
