How to create SSO enabled app for Teams meetings and calls in React

Question

What are some resources that can help me build a single sign-on (SSO) enabled app for Teams meetings and calls using React? I've tried working with provided samples and the Teams Toolkit, but I'm having trouble getting the Save button to work after configuring my manifest with the correct settings. I want to deploy the app on Azure app service and integrate it with Azure Fluid Relay service.

  "configurableTabs": [
    {
      "configurationUrl": "${{TAB_ENDPOINT}}/index.html#/config",
      "canUpdateConfiguration": true,
      "scopes": ["team", "groupchat"],
      "context": [
        "channelTab",
        "privateChatTab",
        "meetingChatTab",
        "meetingDetailsTab",
        "meetingSidePanel"
      ],
      "meetingSurfaces": ["sidePanel", "stage"]
    }
  ],
  "staticTabs": [],
