In order to embed a twitter feed to your XPRS website you first need to create a widget on twitter.
Go here: https://twitter.com/settings/widgets
Click 'Create new', and run through the configuration settings. When you're done hit 'Create Widget'.
You'll then see a new box with HTML code in it:
Copy that code, and go to your XPRS website.
Add the code to your site using a RAW element. You can find instructions on how to use the RAW element here: https://support.wpagency.io/amp/adding-external-html-code-2/
