before hook

hi 
I am trying to implement [feathers-graph-populate](https://feathers-graph-populate.netlify.app/getting-started.html) but when I want to use [Client-Side Params](https://feathers-graph-populate.netlify.app/getting-started.html#enable-custom-client-side-params)  I don't know where to call the before hook when I am using figbird on the client side .
