How to specify multiple dependencies using --packages for spark-submit?

I found it worthy to use SparkSession in spark version 3.0.0 for mysql and postgres

from pyspark.sql import SparkSession
spark = SparkSession.builder.appName('mysql-postgres').config('spark.jars.packages', 'mysql:mysql-connector-java:8.0.20,org.postgresql:postgresql:42.2.16').getOrCreate()

A list of packages should be separated using commas without whitespaces (breaking lines should work just fine) for example

--packages  org.apache.spark:spark-streaming-kafka_2.10:1.3.0,\
  org.apache.hbase:hbase-common:1.0.0
