Shopify expert needed for quick task (ongoing is possible)

I need to stay on the product page after adding products to the cart.
The sidebar cart should be displayed without redirection to cart page. Please check the sample product.
We are using 2 different product templates
sample: https://store.menudesignshop.com/collections/afteroom-collection/products/afteroom-bench
issue: https://store.menudesignshop.com/collections/sofas/products/eave-sectional-sofa
I need it to be done within few hours.
Please apply if you can meet the deadline.
Thanks
