Clarification on Classy for Salesforce Features and Community Portal Integration

Hi Experts,

We are currently exploring the features of Classy for Salesforce and had a few questions regarding its integration with Salesforce Experience Cloud:

1. Does Classy for Salesforce offer any out-of-the-box components that can be embedded into an Experience Cloud portal, allowing donors to log in and make donations directly from the portal?
2. If we embed a Classy donation form into a website or portal, is it possible to prepopulate donor information on the form once the user is authenticated and logged in?

 Please guide me to better understand this.
