rwmb_meta shortcode to display first image in image_advanced field?

Hi!

I have an image_advanced custom field on a CPT with multiple images associated with each post.

I'm trying to retrieve the url of the first image in the array using the rwmb_meta shortcode to use as a featured image but I'm not sure how to do it.

For single image fields I see we can use something like this:

<img src="[rwmb_meta id='product_images' size='full' attribute='url']">

Is there any way to do the same for the first image in an image_advanced field? Or will I need to create a custom shortcode?

Thanks in advance!
