Launched game Scoreboard

[RangeBanenge]

I want to flexibly set up a scoreboard that works after the start of the game, as is done in the lobby, how can I achieve this?
I mean the skorbord that works when the game is launched.
scoreboard:
enable: true
title: '&a%game%&r - %time%'
bedLost: '&c✘ '
anchorEmpty: '&e✘ '
bedExists: '&a✔ '
teamTitle: '%bed%%color%%team%'

Please help, I want to make it with a resource pack using a symbol.

You can either use scoreboard bundled in SBA (if you want to use that addon) or you can use snapshots of 0.3.0 version where custom scoreboards are already implemented (note that 0.3.0 is still an experimental version). Alternatively you can use any other plugin or an addon which will create the scoreboard for you. We won't be porting this feature to 0.2.x.

In general, I need a placeholder that shows how many players are in a certain team.
