Enable flash in new Chrome browsers (since v71) using Selenium WebDriver

Question

I'm developing automated tests for web application that requires Flash plugin. Starting from Chrome v71 it doesn't allow to enable Flash plugin from selenium. The only way that I found is registry modification on Windows (see this post). How can I do the same on Ubuntu or maybe there is a way to enable flash from selenium webdriver?

Chromedrive: 2.46

Chrome version: 72.0.3626.96

The suggestions like adding the following preferences to ChromeOptions don't work since Chrom v71.

prefs = {"profile.default_content_setting_values.plugins" => 1,
           "profile.content_settings.plugin_whitelist.adobe-flash-player" => 1,
           "profile.content_settings.exceptions.plugins.*,*.per_resource.adobe-flash-player" => 1,
           "PluginsAllowedForUrls" => "hendricks-as3.localhost.bbc.co.uk"
          }
