Currently it is required that the "Allowed File Ending" values are hardcoded when uploading documents to the File Gallery. This rigid setup limits adaptability and increases maintenance efforts, especially when file requirements change frequently.

Proposed solution is to integrate the capability to accept variable values for specifying allowed file extensions in the File Gallery. This dynamic approach will enable administrators or developers to modify accepted file extensions on-the-fly without the need to alter the flow itself, enhancing flexibility and reducing the need for frequent flow modifications.
