whatsapp button hide sticky add to cart button

[Yonatan1]

Hi everyone, the importance of the whatsapp button is very important.
However, unfortunately the button hides a lot of texts and important things on the site and really lowers the user experience, I was thinking about the possibility of adding a WhatsApp button only on the contact page, if possible, how do you do it?
I would love to hear your advice, as store owners/experienced. What conveys credibility to customers the most?

thank you for your answer, this is the store link: Audiox.co.il

note that the store is only meant to be for the israeli customers so i didnt had a deep work on the english/arabic translation
