Josephus will set the stage.
8. For we have not an innumerable multitude of books among us, disagreeing from and contradicting one another, [as the Greeks have,] but
only twenty-two books, (8) which contain the records of all the past times; which are justly believed to be divine; and of them five belong to Moses, which contain his laws and the traditions of the origin of mankind till his death. This interval of time was little short of three thousand years; but
as to the time from the death of Moses till the reign of Artaxerxes king of Persia, who reigned after Xerxes, the prophets, who were after Moses, wrote down what was done in their times in thirteen books. The remaining four books contain hymns to God, and precepts for the conduct of human life.
It is true, our history hath been written since Artaxerxes very particularly, but hath not been esteemed of the like authority with the former by our forefathers, because there hath not been an exact succession of prophets since that time; and how firmly we have given credit to these books of our own nation is evident by what we do; for during so many ages as have already passed, no one has been so bold as either to add any thing to them, to take any thing from them, or to make any change in them; but it is become natural to all Jews immediately, and from their very birth, to esteem these books to contain Divine doctrines, and to persist in them, and, if occasion be willingly to die for them. For it is no new thing for our captives, many of them in number, and frequently in time, to be seen to endure racks and deaths of all kinds upon the theatres, that they may not be obliged to say one word against our laws and the records that contain them; whereas there are none at all among the Greeks who would undergo the least harm on that account, no, nor in case all the writings that are among them were to be destroyed; for they take them to be such discourses as are framed agreeably to the inclinations of those that write them; and they have justly the same opinion of the ancient writers, since they see some of the present generation bold enough to write about such affairs, wherein they were not present, nor had concern enough to inform themselves about them from those that knew them; examples of which may be had in this late war of ours, where some persons have written histories, and published them, without having been in the places concerned, or having been near them when the actions were done; but these men put a few things together by hearsay, and insolently abuse the world, and call these writings by the name of Histories.
Against Apion 1:8
And now 1 Macc 9:27
[

prophets ceased to appear among them.
14:41 [

"And the Jews and their priests decided that Simon should be their leader and high priest for ever, until a trustworthy prophet should arise,
And of course there are Christ's words that also confirm all of this.
IIRC, all of the apocrapha was written after Artixerxes, during the time when the lineage of prophets had ceased. Therefore, all of them are uninspired, unlike God-breathed scripture (aka 66 books).
