Any way to tell Emacs how to open specific URIs?

[Jean Louis <bugs@gnu.support>]

I am using goto-browse-mode to highlight URLs and goto-browse-mode
uses in turn thing-at-point-uri-schemes and that is great.

But what I miss is how to define how to activate those URLs, as I
would like to activate those URLs in those buffers where
goto-browse-mode is is activated.

I strongly need a way to define how to open specific URIs as shown
here and to define some of my own. This will expand the program
capabilities I am making.

Is there any current way to define how to open these URIs?

Is there any plan to define those URIs how to open them?

thing-at-point-uri-schemes is a variable defined in ‘thingatpt.el’.
Its value is
("aaa://" "about:" "acap://" "apt:" "bzr://" "bzr+ssh://" "attachment:/" "chrome://" "cid:" "content://" "crid://" "cvs://" "data:" "dav:" "dict://" "doi:" "dns:" "dtn:" "feed:" "file:/" "finger://" "fish://" "ftp://" "geo:" "git://" "go:" "gopher://" "h323:" "http://" "https://" "im:" "imap://" "info:" "ipp:" "irc://" "irc6://" "ircs://" "iris.beep:" "jar:" "ldap://" "ldaps://" "magnet:" "mailto:" "mid:" "mtqp://" "mupdate://" "news:" "nfs://" "nntp://" "opaquelocktoken:" "pop://" "pres:" "resource://" "rmi://" "rsync://" "rtsp://" "rtspu://" "service:" "sftp://" "sip:" "sips:" "smb://" "sms:" "snmp://" "soap.beep://" "soap.beeps://" "ssh://" "svn://" "svn+ssh://" "tag:" "tel:" "telnet://" "tftp://" "tip://" "tn3270://" "udp://" "urn:" "uuid:" "vemmi://" "webcal://" "xri://" "xmlrpc.beep:

Documentation:
List of URI schemes recognized by ‘thing-at-point-url-at-point’.
Each string in this list should correspond to the start of a
URI’s scheme component, up to and including the trailing // if
the scheme calls for that to be present.
