I have a question. How can I sell the scripts that I have purchased?

[Lightify]

Hello, I am a new member of the forum. I am considering selling 5 applications purchased from Codecanyon at a discounted price on this forum. How should the transaction between the buyer and seller be conducted? Both the buyer and I, as the seller, should feel comfortable. In other words, I will be selling scripts on this forum. How can the buyer securely pay me and trust me? I am new to this.
