Figma Triangle Background Plugin/Tool?

Hello, dear creatives!

I recently switched from Sketch to Figma and I’m currently designing a page that really requires such a background. I was wondering if you have some suggestions on how to make /this/ possible? With /this/ I mean random triangle shape background with gradient on top. I would need 30-40 different ones texture wise, but color can stay the same.
