Abandoned Email Image Resize

Hello, I want to resize product images (eg.: ‘style’ => ‘height: 77px; width: auto;’, …) when the customer receives an abandoned cart email. My images are not the same dimensions (height and width), and since the images look distorted and I cannot change the image size in the plugin settings, I want to make an override in functions.php.

I found file in /woo-cart-abandonment-recovery/modules/cart-abandonment/classes/class-cartflows-ca-email-schedule.php in line 283, ;; … ‘style’ => ‘height: 42px; width: 42px;’… Now, I want override this “height” and “width” in functions.php using a Hook, but I don’t know how. Can you help?
Thank you. M
