Drawing a panel/UI?

Hi, I recently transitioned from another library to monogame, for my game I wanted to create a panel/UI/sidebar where it is stationary on the screen during the gameplay. I searched every single keyword regarding this but all I’ve found was to install another library which I dont want to, I want the ability to customize as it goes. Simple built-in functions/tutorials would be appreciated

Try the “Myra UI”. I believe it is Open Source…

Looks promising, I’ll definitely check it out.
Edit: Looking for more suggestion
