Overview On Lightening. what do I actually need

Hi, I am confused.

I have a PI5, with an external SSD. I have Umbrel installed, with Bitcoin Core fully synced.

I have Electrs installed
Lightening Node installed
Ride the Lightening
and Alby Hub installed.

I am not sure what Alby Hub does and If I need all of these components.
Just looking for a clear way to support the lightening Network

I think I have electrs set up to talk to my wallet on Sparrow
What is the difference between Lightening Node/ride the lightening and Alby ?

What do I need do? do I need Alby Hub? whats its function ? Is the functionality covered in Lightening node ?
