ansible.posix.authorized_key fails to add ssh-ed448 pub keys

[hellcry37]

SUMMARY

Every time I tried to add a ssh-ed448 pub key to my servers it failed, everyt other kind of key works including ed25519 but not ed448.
I've tried with file, with text, every way I could find. It fails with error message:
msg: 'invalid key specified: ssh-ed448 AAAACXNzaC1lZDQ0OAAAADmHz1ranDg5alPMO44M5odpWQzpH47xUYQOxztxGo5ZXwA15J6uuQv9ncRvw/u1rjVEM98fBBH+lYA= ciprian'
