I believe they're suggesting you change the post to a 'Launch HN' post.

This is generally a post of this sorts (https://news.ycombinator.com/item?id=14911467) - you launch your product and show it to the HN community, hopefully getting some customers and valuable feedback!

Oh ok, thanks, but should I just replace "Tell HN" to "Launch HN" part or also change the title ? Because I already made a post when I lauched about it here in hacker news and this was more of thank you and just sharing the happiness of getting the first customer.

I think current title is good since you wanted to thank HN.
