Returning to it's website origin

I need help with the following code:

Paid service


Currently, we have multiple domains for a single product. The problem is that we only have a single contact support page. What we wanted was that every time a customer visited the contact support page, when he clicked the home button, he would then return to his website origin.

For example:

The CX1 was from, and he visited the contact support page, which is There is a home button on the contact support page, and when he decides to go back to his website origin, he just needs to click it.

The CX2 was from, same scenario. When the home button is clicked, he will return to his origins.

The product websites are separate from the contact support page. It is currently run through Freshdesk.
