How can I generate a Rails Active Storage circle image variant? I'm able to generate an image variant which is resized using the below code:

    person.profile_image.variant(resize: "50x50").processed.url.split('?').first 

This generates a url which I will be using in an email, Is it possible to make this variant a circular image. I know it can be done with CSS in the browser but my email provider has no custom css support for the types of email I'm trying to send.
