How to check if a workflow template was called?

[Gilwyad]

I have a set of workflow templates defined on the cluster and many workflows that execute some of them. How is it possible to check if a particular workflow template step was called? In the main workflow? In a workflow template?

I tried many things like:

            echo "nonexistent in workflow parameters1: {{= nonexistent in workflow.parameters }}"
            echo "nonexistent in workflow parameters2: '{{= nonexistent in workflow.parameters }}'"
            echo "nonexistent in workflow parameters3: '{{nonexistent in workflow.parameters}}'"
            echo "var1 in workflow parameters: {{= var1 in workflow.parameters }}"
            echo "var1 in workflow parameters2: {{var1 in workflow.parameters}}"
            echo 'workflow.outputs: {{= workflow.outputs.parameters?["var2"] ?? 'N/A'}}'
            echo 'env: {{$env.workflow.outputs.parameters["var2"] ?? 'N/A'}}'
            echo 'functional step in env: {{var2 in $env.workflow.outputs.parameters}}'
            echo 'steps: {{steps}}'

but I either get an unable to resolve error, or the template doesn't resolve at all, and it shows it verbatim. This: #7401 didn't work either.

My use case is that I have at least two types of workflows, with some common steps where I want to check which type is being executed, inside a workflow template.
