Import existing users from custom auth system (algorithm argon2i)

i tried to import our users from a symfony Mysql app to firebase auth with the auth:import feature.
Our application use the argon2i hashing algorithme and it’s not listed in the support list.
I can’t import ours users for this reason.

anybody know if the argon2i will be supported in the future ?
Any alternative existing for my problem? How can i solve this ?
