What should I use to represent the Gujarati language?

I have someone to help me look into the Gujarati language. I'm in the midst of making a video about it, looking into the history of the language, and how its grammar works. My goal is to try and do this with other Indic languages like Odia, Marathi etc. Usually in the thumbnails, I have flags representing the language + a map of where it's primarily spoken. Bc many states in India dont have flags, what should I use to represent the language?
