But now I have the issue that I have multiple workers with an entry point, and I need to write a handler locally like described here: wrangler

TTTbut we don't want to implement our logic twiceWhy don't you share the workflow logic by abstracting it into a function which can be called by either the Workflow or synchronous endpoint?
