Clutch Widget performance improvement

Hello everyone. Thank you for your interest in this issue.
I am working on improving the website’s performance. Currently, the show me 45 points most time loading request is accorded the clutch widget. I already add defer attribute, and this helped a little, but it is still not good for my client.

If there is any idea how I can improve my website performance?

I will appreciate any ideas.
Thank you.
