Flowbite

I'm looking for a library that can allow customization, relatively low effort integration with TypeScript, and ability to bring business users into the design process with a tool like Figma design. We are developing our own SDK for quick dev setup through Open API and build with Webpack and mustache templates. I know Flowbite comes with Typescript definition files out of the box but not nearly as supported as Material-UI. I need to understand what additional work having something that definitely will have long term support like Material UI converted into Typescript vs Flowbite that will have less support, but a typescript definition file out of the box, and what customizing components will do to the type definition files.
