I have seen Elsevier journals offer Gold open access and Green open access options, when I was checking for journals related to Mathematics and Computer Science.
I have understood that Gold open access can be gained by making a publication fee. However they have mentioned that waivers are offered for countries eligible for Research4Life program.
Can someone help me to understand whether you have to be a part of some program to have this waiver? i.e. if you are in a country mentioned in the Research4Life program page in Elsevier, do you get free publication open access in Gold open access journals?

And do Elsevier and Springer offer reductions or discounts in Article Processing Charges for low income countries?
Can someone please advise if you are aware of this.
Thanks a lot in advance.
