Hi stimulus,
If you want to show the main menu beside the logo as a normal template, you can go to the Backend > Template styles > Default style > Layout and edit the Mainnav block.
Click edit block.
And find the line 25:
Replace this code:
<div class="t4-navbar col-1 col-lg-6 col-xl-6 d-flex justify-content-center collapse-static d-none">
With the following code:
<div class="t4-navbar col-1 col-lg-6 col-xl-6 d-flex justify-content-center collapse-static">
Result:
