Upload 2 Products to Platform

Hi, I need assistance with uploading 2 products to a platform. I haven't used my account in 6 months, and the account I wanted to use required an application, which I didn't complete last time. I need someone to guide me through the process of reactivating my account and successfully uploading the products. The ideal candidate should have experience with e-commerce platforms and be able to troubleshoot any issues that may arise during the process.
