Magento 2 M2E Pro Product Description Error

Club Urban uses Magento 2.3.4 and runs a plug-in called M2E Pro to manage listings for e-commerce platforms like Amazon and eBay. We use a template for our product description that gets added on M2E pro-eBay and gets pushed to eBay. Issue: Adding the custom code on M2E Pro causes an error where it won't take the script or style tags. Attempting to add inline style tags causes Magento to ignore them and delete them when going back to review the code. When we do add them we also receive an error code about [unknown object].fireEventReducer(). We know that this is not an M2E Pro issue but rather a Magento issue We require either to format the code so that Magento takes the code and gives the same look we've had or adjust Magento to allow CSS/JS tags to style it. Please review the video showing the problem and I've listed images of what the eBay description is supposed to look like and what we have at the moment without the style tags. Temporary access will be given a few days after accepting the task. We will also be giving the original code.
