How to enable the use of a module downloaded from Qt version 6.2.3 in a project using version 6.2.1?

Good evening to the community, I recently downloaded the "QWebEngineWidgets" module from Qt in order to use it in a project from version 6.2.3 of Qt thanks to the maintenance tool. However, I am using Qt version 6.2.1. I found that my IDE (namely Qt Creator) only reads folders and files from this version and not those downloaded from another version. Which means that although I downloaded this module, my IDE writes the error message saying that this module is unknown. I thought I needed to import the folder from Qt-6.2.3 , but I couldn't do it. So I'm asking what I need to do to use a 6.2.3 module in a project using 6.2.1 modules. Here is a screenshot of my .pro file, you will notice that there is a line where it says "import Qt-6.2.3" (first line):

Thank you !
