Windows Terminal profile or action to open 4 tabs (2x2) in a new tab?

Question

I want to create an action or a new profile which opens 4 new tabs in a 2x2 layout. But I've several issues with this:

My profile just won't open inline with the terminal but always in a new window.

I cant get it to render a 2x2 grid but a 1x2 with another break in the last tile.

Here is the profile I've created. I've tried the same commandline with the newTab action with similar results.

{
    "guid": "{00000000-0000-0000-0000-000000000005}",
    "name": "myProfile",
    "commandline": "wt new-tab -p \"Foo\" ; 
                       split-pane -H -p \"Bar\"  ; 
                       split-pane -V -p \"Baz\" ; 
                       split-pane -H -p \"Git Bash\" -d \"C:\\foo\""
}

For better readability I've added linebreaks to the code above. they are not in my configuration

Update 1:

I was able to solve the issue with the 2x2 pane layout by using the move-focus command. I think this is a preview feature only atm.

{
    "guid": "{00000000-0000-0000-0000-000000000005}",
    "name": "myProfile",
    "commandline": "wt new-tab -p \"Foo\" ;                        
                       split-pane -V -p \"Bar\"  ; 
                       move-focus left ;                       
                       split-pane -H -p \"Baz\" ; 
                       move-focus up ;
                       move-focus right ;
                       split-pane -H -p \"Git Bash\" -d \"C:\\foo\""
}

This is 4x4 profile in the same window:

{
  "commandline": "wt -w 0 new-tab -p \"Foo\" ; split-pane -V -p \"Bar\"  ; move-focus left ; split-pane -H -p \"Baz\" ; move-focus up ; move-focus right ; split-pane -H -p \"Git Bash\" -d \"C:\\git\"",
  "guid": "{e4554b48-406d-4615-98a0-fadd035e6cac}",
  "hidden": false,
  "name": "4x4"
}
