SAWOL isnt really setup for that as you cannot await the return values from the action and then perform further actions on them. I built a plugin that can help with that:
You would need to expose the creation of Thing that is in the List of Things as a backend Workflow that returns the created thing so you can access it via API
If you follow instruction in the plugin, you can read out & select the bubble IDs from the things generated via eg. Thing’s uniqueID is in Step 1’s key1_text .
let me know if you need assistance
