Connect Wordpress website in subfolder of platform application

Hello,

I need some doubts on how to approach a specific task at hand. I have a platform project hosted on AWS amplify, which we later are going to be connecting to a domain like www.testplatform.com . The platform is not connected that domain yet. At the moment we have created a wordpress site which we want to connect to the following domain www.testplatform.com/newsite . How can we have the platform hosted at the first endpoint and the wordpress site at that subfolder? In terms of configurations what needs to be taken into consideration. I am not very knowledgeable in this matter, so thanks in advance for the guidance
