    The script from line 151 to 201 is about getting getting accessToken from Okta and inputing it to Jitsi.

    From this app https://d1n7j1lsem6fu8.cloudfront.net/sa/my-team?organizationId=1, I saw okta writes accessToken into localStorage and I can use that to authenticate.

    Also, debugging Jitsi code I found two entries on localStorage are read by Jitsi: xmpp_username_override and xmpp_username_overrideand I can hook on these to provide authentication info to Jitsi.
