How to best extend url handling

[tott]

Does this feature exist in Emacs orgmode core?

N/A

Orgmode link

I am working with neomutt/notmuch and have methods to add todos/notes directly from emails and would like to extend OrgMappings:open_at_point() at https://github.com/nvim-orgmode/orgmode/blob/34b9261145ba558c233450a0a81512fbb56b25a5/lua/orgmode/org/mappings.lua#L643 but I could not find any good way to add custom URL handlers in this method. What would be the best way to extend this functionality to handle a new link format (in my case [[message://....]])?

Feature value

Support for access to additional external links and easier integration between orgmode and other systems.
