"I can't add MySQL users because I have reached the maximum number of additional settings that can be added." Explanation of how to add [X Server]

X Server recently allowed an unlimited number of MySQL users.
This allows both MySQL database and MySQL users to use it unlimitedly, and our production members who often use X Server are very happy about this!
The other day, I had the opportunity to install WordPress and tried the easy installation of X server...
cannot be added because the maximum number of MySQL users can be added.
Eh, isn't it unlimited...
For some reason, an error came out and I couldn't create a new database, and because of that, WordPress couldn't be installed.
what is it, X-Server liar?
When Ilooked into the measures, it seems that all subscribers have the right to use it unlimitedly, but it seems that it is necessary to apply to the X server in advance to relax the upper limit.
It's true that if everyone uses it unlimitedly, the server load won't be bad. I'm sorry for thinking you're a liar.
So how do I apply?
When I sent a request to relax the limit for MySQL users through the inquiry form of X Server, I was asked to reply by describing the name of the subscriber, the number of people I want to add, and the purpose of using MySQL.

It was said, "We can't relax more than 200 at a time," but 200 is quite a number. By the way, I asked for an additional 50 at this time.
(If you fill out the inquiry form from the beginning and send it, you may save a little time, but I haven't tried it.) )
After applying, they worked on the X server side, and I was notified of completion, and I was able to install WordPress safely.
