A Main GUI must be defined; otherwise, the plugin will not work.
Congratulations on creating your first setup! This is the last step to bring your inventories into reality. It's super simple: open your config.yml and follow the provided scheme to finalize each Custom GUI. Once you're done, save and execute /identity reload or restart your server.
guis:
<inventory-id-name>:
path: "inventories/selector.yml" # Relative Path, starting from plugins/Identity
type: SELECTOR # SELECTOR, VALUE, INPUT, MAIN
mandatory: true # true or false, if it must be completed
displayName: "First Inventory" # This is what will be displayed when you're closing or confirming the Main GUI,
# and this one is not completed but mandatory.
# Value Menu Only Properties
base: 1 # The base value
min: -10 # The minimum value
max: 20 # The maximum value
