How to give a review to seller after 5 days

[hazel_justin131]

A buyer bought my gig and was happy with my service but he couldn’t leave a review at that time. After 5 days, he is asking how can he give me a review and he did not find the review button on the order page?
Does somebody know how to give a review after some days have passed
