Hello,
Thank you for contacting Rank Math support today.
Unfortunately, we don’t have any control over how SERP results are displayed and Google displays them as per their will.
Please refer to this article: https://moz.com/learn/seo/serp-features#image-pack
Here is a similar inquiry on google support: How to display pictures in the mobile SERP
With that said, although Rank Math generates a proper schema and meta tags, it is ultimately Google’s decision if they want to include them with your website or not. It depends on a lot of factors, authority and backlinks being just the 2 of them.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
