No, it is not.
My experience says: send email to support, get request ticket, then create a post in "Question and Support". Moderator (his nick is "No Time To Play") will read it and resend to administrator. And only after all those actions, maybe (maybe!) your games will be reindexed.
This is one of my story: https://itch.io/t/5441904/please-reindex-my-games-i-wait-80-days for an example.
Good luck.
