How do I run an ijm script?

I'm attempting to run an ijm script by changing the example that runs a python script.

The script I'm attempting to run is as follows:

```
run("Set Scale...", "distance=4.585 known=1 pixel=1 unit=µm");
setAutoThreshold("MaxEntropy dark");
setOption("BlackBackground", true);
run("Convert to Mask");
run("Despeckle");
run("Watershed");
run("Analyze Particles...", "size=16-Infinity circularity=0.50-1.00 display exclude summarize");
```

I tried setting `language` to `ijm` and `in1` to the script but that caused an error. I tried escaping the quotes, parentheses, and replacing the newlines with `\n` and that still caused an error. I tried changing `in1` to be `script` and removing `in2` and I'm still seeing errors.

Any help would be appreciated.

The issue includes an IJM script and describes failed attempts involving language, in1, and in2, but names no repository file, endpoint, or complete failing request. Start by comparing the request used for the Python example with the information provided here. Done means establishing the correct way to submit this script or documenting the missing request details needed to diagnose it.
