Perplexity pro coupon code

I meet the requirements for the one year of free Perplexity pro and I can't find the coupon code anywhere. Can you please help? Here's the page with details: https://www.perplexity.ai/hub/blog/redeem-a-free-year-of-perplexity-pro-through-xfinity-rewards

also ive been looking at other posts, and a lot of them talk about direct messaging support, but i do not see a direct message icon or button in my browser for that.
