at first i saw this but imo more explicitly something like this:

How i get it:
1. make cfg with one temp handy bind:
bind mouse5 "kick all; bot_pause 0; wait 10; addbot keel; addbot keel;addbot keel;addbot keel;addbot keel;addbot keel; addbot keel; addbot keel; addbot keel; addbot keel; addbot keel; addbot keel; wait 10; bot_pause 1"
2. start practice match against bots at any map with maximum total players
3. /devmap terminatria (devmap needs for bot_pause 1 - bot stays at spawn)
4. exec cfg
4. spectate (freecam) and press that bind.
