I started to build my first Figma plugin and stacked to install Tailwind,,,

Hi guys. I’m the beginner developer who just started to develop on Figma Plugin.
Although Figma plugin UI window is the single page, I was able to install React. However, I’m stacked with installing Tailwind,

I don’t know why, but my UI window does not apply Tailwind CSS style.
Can anybody help me to install Tailwind?
