In the directory your configuration.yaml file is location, create a folder called custom_components and put group_globber.py there. Then inside your configuration.yaml file, add a section like so:

group_globber:
  groups:
    group.group_emby:
      - media_player.emby*
      
You should probably already have the group, in this case "group_emby" already created somewhere. Then you can add a list of wildcards that'll match entities and put them in that group.

Note: I have not tried modifying the built in "all" groups and I have always had the group I want to add things to already created.
