Is this an extension for Azure Data Studio?

This extension is in the list for Azure Data Studio Marketplace extensions, but when I try to install it the installer says it is for VSCode only.

Hi @twoeskeide,
You can't install the theme by double-clicking the .vsix file directly.
You can open Azure Data Studio, then go to File -> Install Extension from VSIX Package, then choose the .vsix file.
