@Marvin Based on this concept, how can I update/modify variables? https://docs.prefect.io/latest/guides/variables/#managing-variables

To update or modify variables in Prefect, follow these steps: - Variables are named, mutable string values and can be created or modified at any time. - They are intended for values with infrequent writes and frequent reads. - Variable values are most commonly loaded during flow runtime but can be used in other contexts. You can find more detailed instructions and examples by visiting the Variables section of the Prefect documentation: Managing Variables. The guide includes how to create, modify, and use variables within your Prefect instance or workspace.
