Thank you for posting your query on Microsoft Q&A, PFB answers to your queries:
- In Step #1, do I only need to prepare the data connector related resources in JSON format files without concerning with the deployment framework?
Yes, you just need the data connector related resources in JSON format files, deployment package contains all the template files needed for this plan, as well as any additional resources, packaged as a .zip file.
- After the PR is validated, will the ARM template files (mainTemplate.json and createUIDefinition.json) be automatically generated? Additionally, at that point (step #2), can I manually modify or add extra details such as '"outputs": { blahblahblah }' and other elements to the deployment Template JSON? No, this will part of solution template which would contain Deployment package
If you don't have any further queries and the suggested answer is as per your business need, please "Accept the answer", This will help us and others in the community as well.
