how can I get to chrome Options preference arguments like profile.content_settings.exceptions.plugins ?

[soulgoon]

While crawling with selenium in a python environment, I had to use flash in the chrome webdriver.

I tried to find a setting that would allow Flash.

The three links below are the information I found.

• https://www.chromium.org/administrators/policy-list-3#PluginsAllowedForUrls
• https://peter.sh/experiments/chromium-command-line-switches/
  https://chromium.googlesource.com/chromium/src/+/master/chrome/common/pref_names.cc
  

After all, I did not find a clear answer, I found the question on the stack overflow and solved it.

The contents are as follows. https://sqa.stackexchange.com/questions/30312/enable-flash-player-on-chrome-62-while-running-selenium-test

 ChromeOptions options = new ChromeOptions();
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("profile.default_content_setting_values.plugins", 1);
prefs.put("profile.content_settings.plugin_whitelist.adobe-flash-player", 1);
prefs.put("profile.content_settings.exceptions.plugins.*,*.per_resource.adobe-flash-player", 1);
// Enable Flash for this site
prefs.put("PluginsAllowedForUrls", "https://arlo.netgear.com");
options.setExperimentalOption("prefs", prefs);  

My question is this.

1) Where can I find information like

• profile.default_content_setting_values.plugins
• profile.content_settings.plugin_whitelist.adobe-flash-player
• rofile.content_settings.exceptions.plugins.,.per_resource.adobe-flash-player

2) How can I confirm that it is official information?

If you have any other way to find this information, please let us know about your keywords.

I want getting refs arguments list.
