Undo the purchase operation [timed option]

[comonier]

My native language is Portuguese so I will use the translator.

It's been happening a lot among players on the server where I play, complaining about having accidentally bought something because they didn't read the price correctly, they thought it was the unit and bought it in packs, or they thought it cost 1000 but it cost 1,000,000, that is, if they regretted making a purchase.

I would like to know if it is possible to add that after a player buys any item, whether from another player or from the server's store, he can have time to regret it, returning what was purchased to the store and getting his money back.
