You can make change to it using the editor, and click “Apply changes” to make your change effective. ## Export running simulations You can also export the simulation in an active service for future sharing or reuse, especially the simulations are created via capturing. Click on the dropdown menu in the toolbar and select “Export simulation as new\...”, it will prompt you for the simulation name. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
