What are the available file types rather than 10-Q?

Hello LESG Dev Team,

I am working on a project to retrieve annual reports of emerging countries firm. The sample I am following shows the retrieval process of TSLA.O which have 10-Q report. I want to download annual report pdf files. For example BRAC.DH "Full Year" report. In the query FilingsQuery().form_type("10-Q") what should I put instead of "10-Q"? is there any list of options available?
