How to use proxy with Snowpark session builder to connect to snowflake - scala

Question

I am new to using snowpark, recently released by Snowflake. I am using Intellij to build udf(user defined functions). However struggling to use proxy using Intellij to connect to snowflake. Below are few things I already tried:
putting proxy in Intellij (under Preferences)
adding proxy before building session
System.setProperty("https.useProxy", "true")
System.setProperty("http.proxyHost", "xxxxxxx")
System.setProperty("http.proxyPort", "443")
System.setProperty("no_proxy", "snowflakecomputing.com")
Below is my code -
val configs = Map (
"URL" -> "xxxxx.snowflakecomputing.com:443",
"USER" -> "xxx",
"PASSWORD" -> "xxxx",
"ROLE" -> "ROLE_xxxxx",
"WAREHOUSE" -> "xxxx",
"DB" -> "xxxx",
"SCHEMA" -> "xxxx",
)
val session = Session.builder.configs(configs).create

Snowpark uses JDBC driver to connect to Snowflake, therefore the proxy properties from JDBC connector can be used here as well.
In your Map add:
"proxyHost" -> "proxyHost Value"
"proxyPort" -> "proxyPort Value"

If you're specifying a proxy by setting Java system properties, then you can call System.setProperty, like:
System.setProperty("http.useProxy", "true");
System.setProperty("http.proxyHost", "proxyHost Value");
System.setProperty("http.proxyPort", "proxyPort Value");
System.setProperty("https.proxyHost", "proxyHost HTTPS Value");
System.setProperty("https.proxyPort", ""proxyPort HTTPS Value"")
or directly to JVM like:
-Dhttp.useProxy=true
-Dhttps.proxyHost=<proxy_host>
-Dhttp.proxyHost=<proxy_host>
-Dhttps.proxyPort=<proxy_port>
-Dhttp.proxyPort=<proxy_port>
