Selenium Manager can't download through proxy

I'm behind a company proxy and am normally able to do anything if I just point to it(no user/pass required). I've tried about all the different options to set it, the last one was the example of the docs here: https://www.selenium.dev/documentation/webdriver/drivers/options/#proxy

But every time there's a Geckodriver update I run into the same NoSuchDriverException: Message: Unable to obtain geckodriver using Selenium Manager: Message: Unsuccessful command executed. Error sending request for url (https://github.com/mozilla/geckodiver/releases/latest): error trying to connect: tcp connect error: something something os error 10060.

Does setting the webdriver desiredcapabilities proxy even have an effect on the selenium manager that downloads the new driver?
