Shared pipelines - how to use multiple steps

[shainegordon]

As referenced here https://support.atlassian.com/bitbucket-cloud/docs/share-pipelines-configurations/ , I'm able to import and use a custom manually triggered step in our pipeline

pipelines:
  custom:
    create-master-to-develop-pr:
      import: automation-scripts:master:create-master-to-develop-pr
    create-release-branch-and-pr-into-master:
      import: automation-scripts:master:create-release-branch-and-pr-into-master
    intent-architect-ensure-no-outstanding-changes:
      import: automation-scripts:master:intent-architect-ensure-no-outstanding-changes

this works great.

however, I want to also use these in branch specific steps

e.g.

branches:
  '{develop}':
    - step: *deployDev
    - step:
        import: automation-scripts:master:intent-architect-ensure-no-outstanding-changes

the bitbucket-pipeline.yml validator says this is "valid", but when these is executed, there we get an error

`No commands or pipes defined for the step at [pipelines > branches > {develop} > 1 > step]. Check that you have defined a valid "script" section.`

This is how our shared pipeline is defined:

export: true

definitions:
  pipelines:
    intent-architect-ensure-no-outstanding-changes: &intent-architect-ensure-no-outstanding-changes
      - step:
          name: Intent Architect CLI - ensure-no-outstanding-changes
          image: mcr.microsoft.com/dotnet/sdk:9.0
          caches:
            - dotnetcore
          script:
            - dotnet tool install Intent.SoftwareFactory.CLI --global
            - export PATH=$PATH:/root/.dotnet/tools
            - intent-cli ensure-no-outstanding-changes $INTENT_USERNAME $INTENT_PASSWORD ./intent

Is it possible to do what I want?
Share steps on custom pipelines, and also as additional steps in branch piplines?
