Scott Joplin's Influence on European/Classical Composers in the early twentieth century?

Hi everyone, I'm currently doing an essay on Ragtime/Scott Joplin's underrated impact on Jazz and Classical music at the turn of the century, and I wanted to know the validity of his supposed influence on composers like Debussy.

I've read several online articles that say this alongside a few "academic" papers from a Google Scholar search, but all of them lack depth and don't elaborate on whether someone like Debussy specifically heard any of Joplin's piano rags.

I'm aware that Europeans (particularly the French) were fascinated with the Cakewalk dance, and Ragtime certainly made its way over there, but I can't find anything specific about Scott Joplin.

any sources/help/recommendations would be appreciated :))

Thanks.
