Kibana minimalistic view

We have an unstructured ELK stack with 100s of fields, hosts and types.

I like to create a minimalistic view where user can only choose a few fields and hosts and keep all the rest hidden away. Not by giving the long complex url to what to search.

Can this be done by adding a specific user and roles in the free version v7.3 where we now have users and roles?

I've earlier used elastics restapi directly with a simple webservice.

Yes, for sure you can use Users and Roles and create a specific user with an associated role only to access few fields as defined

You can give access to only specific indices as defined:

Thanks and let us know how we can help further,
