Overview

OmniAuth strategy for Zoom (zoom.us) OAuth 2.0.

Vendored verbatim from the abandoned omniauth-zoom gem (last
released 2021). That gem's newest version pinned
omniauth-oauth2 ~> 1.7.1, which conflicts with the
omniauth-oauth2 ~> 1.8 required by omniauth-google-oauth2 and
omniauth-linkedin-openid — so the gem was frozen at the 0.2.1 era
and could never be upgraded. Vendoring the ~50-line strategy
drops the dependency entirely and lets it run on the current
omniauth-oauth2 (1.9.x) like every other strategy. Behaviour is
identical to omniauth-zoom 0.2.1, which already ran against the
installed omniauth-oauth2 1.9.x.

Loaded via an explicit require in config/initializers/130_devise.rb
(the lib/omniauth directory is excluded from Zeitwerk autoloading
in config/application.rb — omniauth does not match the default
Omniauth inflection and reopening a gem-owned namespace under an
autoloaded path is unsafe).
