Regarding changing image of published app

Will I have to republish my app and go through review process once more after I change the image.

Hi @shravanbharatdoda
Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!
If you are only changing the image of your app, then the process is very straight forward, you just need to resubmit your app for review and it normally only takes a couple of days for a reviewer to get to your app and approve the new image/
