how do I hard purge/force purge a cdn jsdelivr file

here's the issue: i distributed my specific github file link to the public, and now there's a critical issue in which i NEED to update that file's contents. however i cannot purge it for the life of me. ive been on vpn, private browsing, even the tor browser using jsdelivr.com/tools/purge and the raw purge.jsdelivr.net endpoint. i've waited out the throttle and done the same - the file remains in its old version. i need a one-and-done, immediate method to just force jsdelivr to update the cache to the newest version from my github.
