Call Django command with phrase as argument

I'm trying to run the command

zappa manage staging 'run_sql --sql \"show databases\"'

But I get the following error:

zappa manage staging 'run_sql --sql "show databases"'

django.core.management.base.CommandError: Error: unrecognized arguments: databases

I tried various things like

zappa manage staging 'run_sql --sql \"show databases\"'
zappa manage staging 'run_sql --sql \\\"show databases\\\"'
zappa manage staging 'run_sql --sql \"show\ databases\"'
zappa manage staging 'run_sql --sql \\\"show\\\ databases\\\"'

But all fail for the same reason:

django.core.management.base.CommandError: Error: unrecognized arguments: databases\\”

It looks like Django command parser believes the phrase are several options or something, but I can't figure out the way to treat it as a single argument.

Based on the following Django Command:

import MySQLdb as db
from django.conf import settings
from django.core.management.base import BaseCommand


class Command(BaseCommand):
  help = "Runs a raw SQL query"

  def add_arguments(self, parser):
    parser.add_argument(
      '--user',
      dest='user',
      help='Username to be used to create database',
    )
    parser.add_argument(
      '--password',
      dest='password',
      help='Password for the mysql user.',
    )
    parser.add_argument(
      '--db-name',
      dest='db_name',
      help='Name of the database if it is different from the one defined in settings',
    )
    parser.add_argument(
      '--sql',
      dest='sql',
      help='SQL query to run',
      default='show databases'
    )

  def handle(self, *args, **options):
    self.stdout.write(self.style.SUCCESS('Running raw SQL query'))

    sql = options.get('sql')
    dbname = options.get('db_name') or settings.DATABASES['default']['NAME']
    user = options.get('user') or settings.DATABASES['default']['USER']
    password = options.get('password') or settings.DATABASES['default']['PASSWORD']
    host = settings.DATABASES['default']['HOST']

    self.stdout.write(self.style.SUCCESS(
      'Running SQL query\n'
      '"{sql}"\n'
      'with \n'
      'dbname="{dbname}"\n'
      'user="{user}"\n'
      'password="{password}"\n'
      'host="{host}"\n'
      ''.format(
        sql=sql,
        dbname=dbname,
        user=user,
        password=password,
        host=host,
      )
    ))

    con = db.connect(user=user, host=host, password=password)
    cur = con.cursor()
    cur.execute(f'{sql}'.format(sql=sql))

    output = cur.fetchall()
    self.stdout.write(self.style.SUCCESS(
      "\nSQL query output:\n"
      "{output}".format(output=output))
    )
    self.stdout.write(self.style.SUCCESS('\n'))

    cur.close()
    con.close()

    self.stdout.write(self.style.SUCCESS('All Done'))
