How to disable iframes on the wix website

Hello All, I have recently created a website through wix.com, https://www.drshwetabhatia.com I am trying to optimize the website to improve the ranking on google.
Through various seo checkers available online, I keep getting this warning that my webpages use iframes.
I am very new to website programming and HTML.

Would it please be possible to advise on how to disable iframes and if you have any other suggestions to improve the site’s ranking…

Thanks a lot in advance for all your help!!
