Set Work Area to Selected Layers with script, command id

How to "Set Work Area to Selected Layers" with a script? 
app.findMenuCommandId("Set Work Area to Selected Layers") writes 0.
Or if there is no way, how to trim comp to selected layers area. I wanted to set the work area to selected laters and then trim comp to the work area. But if there is no way to do these two things with a script, how to achieve this with short steps?

the command number for trimming the comp to the work are is 2360.

i couldn't find a command number for setting the work area to the selected layers.

Here is an Automation Blocks script to set the workarea to all selected layers:

See this post for more details.

If you want to script it yourself without Automation Blocks, you can use the same logic for your js code.
