How to assign authentication mechanism to user in MongoDB

I created a user in MongoDB using 

db.createUser({user:"admin", pwd:"admin", role : [{role:"readWrite", db:"someDB"}]});

But I assume this user has been created with the default authentication mechanism. So if I want to authenticate only using, lets say SRAM-SHA-256, I tried doing

db.createUser({user: "test", pwd:"test", role:[{role:"readWrite", db}], mechanisms: [ "SCRAM-SHA-256" ]})

But this doesn't seem to work. It is throwing an error

Error: couldn't add user: "mechanisms" is not a valid argument to createUser

How to do this ? I am using MongoDB version 3.6.18

You are getting the error because MongoDB version 3.6 doesn't support the mechanisms argument for db.createUser() function, you can check that in MongoDB 3.6 Doc

And also the mechanism SCRAM-SHA-256 you are trying to implement doesn't work in MongoDB 3.6, it was introduced in MongoDB 4.0, you can check that on SCRAM-SHA-1 and SCRAM-SHA-256 DOC

And as written in the latest MongoDB Docs, by default in 3.6 it's SCRAM-SHA-1 and you can't change it.

mechanisms - The default for featureCompatibilityVersion is 3.6 is SCRAM-SHA-1
