How to use applyFilter?

Hi, can you make an example on how to use the applyFilter function?

What I tried so far:
applyFilter(() => true);

Error message:
```
TypeError: filters[j] is not a function
    at Object.applyFilters (C:\Users\ian\work\capture-movement\node_modules\.pnpm\@vibrant+image@3.2.1-alpha.1\node_modules\@vibrant\image\lib\index.js:42:32)
```

Thanks
