How to setup custom apps using the develop branch for the apps

[elhananjair]

Hello there, I was trying to experiment with the ERPNext 16 beta and for other custom apps too, like HRMS, LMS and Helpdesk. I tried to change images/layered/Containerfile FRAPPE_BRANCH to develop, and used a beta tag in apps.json

[
  {
    "url": "https://github.com/frappe/erpnext",
    "branch": "v16.0.0-beta.2"
  },
  {
    "url": "https://github.com/frappe/hrms",
    "branch": "v16.0.0-beta.2"
  },
  {
    "url": "https://github.com/frappe/helpdesk",
    "branch": "develop"
  }
]

The podman build I have used is this:

podman build \
  --no-cache \
  --build-arg=FRAPPE_PATH=https://github.com/frappe/frappe \
  --build-arg=FRAPPE_BRANCH=v16.0.0-beta.2 \
  --build-arg=APPS_JSON_BASE64=$APPS_JSON_BASE64 \
  --tag=custom:16-beta \
  --file=images/layered/Containerfile .

Can someone suggest me if there the right way to try beta versions of custom apps?
