[SHOPIFY Fix] - Little work and Website Optimization (Minify, Defer, LazyLoad etc...)

Hello,

Website: https://www.madameprovence.com/collections/meilleures-ventes/products/1

Work:

1. https://imgur.com/a/KZJQ1wh (for all desktop/laptop and tablets, NO MOBILE)

2. Click on cart icon. I want the text "Retourner sur la page produits" to close the cart drawer.
= do same action as "close" button or same action as when touch/click anywhere outside cart drawer.

3. Optimize website speed.

Theme is already fast but I want to optimize more:

Optimize images, remove unused CSS, JS or whatever script, defer correctly code and clean it, remove unnecessary files so all is really clean and there is no blocking time nor delay and website is super fast.

As I said, website is already optimized so it's not "too much work".

If you can do the 3 tasks, please send me a message with your price and timeline, looking for a good price and fast timeline for this project.

Also looking for long term collaboration.

Thank you
