OAuth from plugin

Is there any existing way in the plugin SDK to use OAuth to authenticate? I found these existing threads on the topic:

https://intellij-support.jetbrains.com/hc/en-us/community/posts/206755005-WebView-into-Intellij

but neither seemed to indicate an existing facility. Since those were asked several years ago, I figured I'd see whether there might be new information.

Obviously I can host my own form to capture username and password to send to the OAuth token endpoint, but ideally it would occur in a browser to enhance the trust relationship.  I could use a Swing-based Web view, but I'm not sure how well it would render the authentication form.

Has anyone done this from a plugin? Any thoughts on how it can best be accomplished?

Thanks in advance for any thoughts!
