So far I ended up with the following:

  • bitrise.yml in web - accepts call and dispatches to actual workflow in repo:
---
format_version: '7'
default_step_lib_source: https://github.com/bitrise-io/bitrise-steplib.git
project_type: other
workflows:
  ci:
    after_run:
    - run_from_repo
  run_from_repo:
    steps:
    - activate-ssh-key:
        run_if: ''
    - git-clone: {}
    - script:
        title: continue from repo
        inputs:
        - content: |-
            #!/bin/bash
            set -ex
            echo "workflow to run from trigger: ${WORKFLOW_TO_RUN:-primary}"
            bitrise run "${WORKFLOW_TO_RUN:-primary}"
  ios:
    after_run:
    - run_from_repo
    steps:
    - script@1.1.5:
        inputs:
        - content: |
            #!/usr/bin/env bash
            # fail if any commands fails
            set -e
            # debug log
            set -x

            envman add --key WORKFLOW_TO_RUN --value ios
  android:

I wish this kind of a set up was a bit more straightforward…
