How to run nf run 'node --expose-gc' app.js

Hi, trying to run a node script with `--expose-gc`. How would this be possible? Can't find an example in README.
```
nf run 'node --expose-gc' app.js

gives
/bin/sh: line 1: node --expose-gc: command not found

nf run node --expose-gc app.js

gives
error: unknown option `--expose-gc'
```


Thanks!
