Hi there! My name is, Zadee. I'm an Independent Advisor and a Microsoft user like you. Sorry to hear about your experience. I'll try my best to help you today.
I've searched all over the internet, I can't seem to find that keyboard you are referring to in the google search box, not even on youtube. Perhaps that's only available in specific regions. OR you might just be referring to the Google Input keyboard extension? Because that's what I downloaded, and now I'm able to change my keyboard layouts not just on those specific sites but to any sites I visit. Perhaps that workaround works for you. You can download the extension here.

You can also, by the way, change the keyboard layout directly from your windows device simply by going to Settings > Time & Language > Language. Under Preferred languages, select the language that contains the keyboard you want, and then select Options. Select Add a keyboard and choose the keyboard you want to add

Hope that helps.
