In the documentation, we don't have a lote of details of how to use firebase notification;
We only have a description in helpers ( https://github.com/crocodic-studio/crudbooster/blob/master/docs/en/helpers.md )
But what is : $regid = ['REGID_GOES_HERE','REGID2_GOES_HERE','ETC...'];
Where can I find this Ids;
`// You can add more key as you need
// $data['your_other_key'] =`
Where can I find other keys ?
Do you have any exemple or tutorial about this ?
