Is there a way to also limit the plugin from getting prompt values if it is already running

Is there a way to limit the plugin UI from getting prompt values if the custom recipe is already running in a flow?

Let set the stage:
I have created a plugin custom recipe to export a tableau worksheet as an PDF for each partner.
the list met partners is provided by an input step and the PDF's are saved to a managed folder.

Because of the Tableau PAT limitations you can only use 1 session at a time and if a new session is created with the same PAT the running session is disconnected with an authentication error

To limit the concurrent executions of a custom recipe in a flow DSS has the resourceKeys method and that seems to work for the recipe but will not block the plugin configuration calling the prompt values.

One thing about the tableau server API is that if you can use basic auth, you can bypass the single session requirement. This is a workaround of course but it does work and is more reliable than using a PAT. Tableau has a terrible implementation with the single session PATs and orchestration tools like DSS and Airflow struggle with this concept. If you must use PATs, you will essentially need to create a pool and manage the PATs akin to: https://github.com/tableau/server-client-python/issues/717

You'd need to at least set up a PAT and a backup for your plugin. Then you'll need to rotate them periodically as well based on your tableau admin requirements. A lot of overhead.

They blocked basic auth so PAT seems to be the only option.

I will investigate the pool of tokens options.
