Are there any more books of the bible that we don't know about?

Scholars believe there may be other texts that were written during the time the biblical canon was formed but were not included in The Bible. Some of these texts, often referred to as apocryphal or deuterocanonical books, were excluded for various reasons, such as lack of widespread acceptance or theological consistency. Additionally, historical evidence suggests that many other writings existed but have since been lost or destroyed. However, the exact number and content of such texts remain speculative.
