How to Create Azure MySQL Flexible Server 8.4 using azurerm_mysql_flexible_server 4.54.0

Hi everyone, I need to create an Azure MySQL Flexible Server with version 8.4 using azurerm_mysql_flexible_server (hashicorp azurerm provider version 4.54.0). According to the documentation, it states:

“version - (Optional) The version of the MySQL Flexible Server to use. Possible values are 5.7, and 8.0.21.”

How should I proceed? When will it be possible to create version 8.4 as well?

Thank you
