How to move logo and menu to opposite sides?

I want logo and menu links be on opposite sides, inside container. I tried make it with flex box
in container, horizontal direction with justify space between, but it will not move to edges of container and have spaces on sides. Any help would be appreciated.

Here is my site Read-Only: [LINK](Webflow - Web 2.0)

If you use a div block instead of a container it should work. Then you can add margin to adjust the space, don’t know why it works like this.
Hope this helps

Thank you for your suggestion.
