Hello YuriyMikitchenko,
Welcome to Microsoft Community.
I am a Microsoft user just like you, I hope you are doing well?
You can see it in the screenshot you attached, Microsoft Editor is currently not supported on Google Docs. I have tried it on my end and the result is the same as the image you shared.
See thread to similar inquiry: https://answers.microsoft.com/thread/0880be4d-2ed5-48be-a400-de84aa2d538c
