How to add two calls to action?

Hi team,

Currently, our email has only one call to action with a link to leave a review at Google My Business.

I’d like to change this and have two buttons there.

If the customer has a Google account, then please leave a review at Google.

If the customer does not have a Google account, please leave an internal product review.

Is this possible?

How can I add another button to the email?

Thank you
