Run Javascript workflow not visible in Bubble.io

I’m using bubble.io and i’m configuring the workflow now and I have a situation to run a javascript to read the values/expressions. I found that Toolbox plugin is helpful to achieve it. But when installed it and when i looked at the from the action list plugin, “Run Javascript” is not visible. Only Server script is visible. Please help.

is that from the backend workflows or page workflows?

backend workflows.

That’s correct then. Run JavaScript on page, use server script in backend

ok. thanks. Let me see how i can use it for reading the expression or prompt from api.
