I have a question. How can I sell the scripts I 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 the 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.
