Creating a user and login or connect new user to existing sql server login with azure cli command? - authentication

Question

I was just wondering if there is a way to create a user and either creating or connect that user to an existing azure sql server login using azure cli?
EDIT:
I would do it with something like this in sql, for example:
-- For login login_name, create a user in the database
CREATE USER <username> FOR LOGIN <login> WITH DEFAULT_SCHEMA = [dbo]
GO
-- Add user to the database owner role
EXEC sp_addrolemember N'db_owner', N'<username>'
GO

You can use below command to run sql query in Azure PowerShell and I followed SO-Thread:
$servername = "sqlservername.database.windows.net"
$databasename = "databasename"
$username = "rithwik"
$pass = "R!th"
$query = "CREATE USER User2 For login xxx WITH DEFAULT_SCHEMA = [dbo]"
$sqlCon = New-Object System.Data.SqlClient.SqlConnection
$sqlCon.ConnectionString = "Server=$servername;Database=$databasename;User ID=$username;Password=$pass;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;"
$sqlCon.Open()
$sqlCmd = New-Object System.Data.SqlClient.SqlCommand($query, $sqlCon)
$sqlCmd.ExecuteNonQuery()
$sqlCon.Close()
Here xxx is the login name.
Then the user is created:
Then you use
$query = "EXEC sp_addrolemember N'db_or', N'<username>'" in place of above $query to add role.
