Is it allowed to give my plugin for free to someone to make a review?

I am an exclusive author and I have one plugin approved. I read the promotion help articles, but I still don’t understand, am I allowed to give to someone (for example a blogger) the plugin so he can test it and then write a review on his blog?

I believe it would be fine

If you want a review license, you have to buy it as per envato helpdesk

Well, paying someone to buy the product (and then make a review) is also not allowed. And if giving it for free is not allowed too, I do not see a way to make someone make a review of the product.
What is this review license? Is this a different license type?
Thanks to both for the answers.
