In odoo12 I want to create a view that only changes something for website 1 and not website 2.

In odoo backend its very simple with the website_id field. But how do I write that in my own module?

Example:

<template id = "test" name="test" inherit_id="test.test_view" priority="16" website_id="1">
<xpath  expr=.....
.... </xpath>
</template>

Doesn't work. What is the right way to create a view that only applies to one specific website and not any other one?
