I'm trying to use extension inheritance to add a message so the user knows how to make the payment when on the payment status page.

I'm using this documentation to help me, but the template doesn't seem to be loaded at all. the way I test this out is via:

<t t-set="helloworld" t-value="helloworld"/>
<t t-log="helloworld"/>

Looking for recommendations on how to get this working.
