How can I enable variations in Chrome from chromedriver options?

Hello, I'm facing a problem with Chrome where when I run an automated UI test with chromedriver, there's issues showing up (such as header is too high which covers other elements) but if I manually open up Chrome and perform the UI tests manually, the issues aren't there (the header looks correct).

I opened up chrome://version for both browsers and saw that the instance from automation does not have Variations listed, while the manual run had Variations listed.

I tried adding options.addArgument("--reset-variation-state) in hopes that it would enable it but it did not do anything.

I'll attach some screenshots Chrome with Variations

This is chrome without Variations Chrome without Variations

So, this kinda worked for me. Currently researching better options.

If you go into C:\users\[username]\AppData\local\Google\Chrome\User Data and find your "Local State" file, there are two entries in there you should see values for -- "variations_compressed_seed" and "variations_seed_signature"

If you copy those values, and add them in your Chrome options before you start ChromeDriver, then variations should be enabled:

chromeOptions.AddLocalStatePreference("variations_compressed_seed", "[your compressed seed]");
chromeOptions.AddLocalStatePreference("variations_seed_signature", "[your seed signature]");

If you don't have those values in your Local State file, you can start Chrome with some dummy data directory, e.g. start > run > chrome.exe --user-data-dir C:/Chrome, then shut down chrome, go to C:\Chrome\ and find the seed and signature in the "Local State" file that gets created in there.
