Technical Flow

1. Plugin checks whether currentUrl is a Greenhouse URL and if so, shows a popup with an email input field and a submit button
2. User submits as prop userEmail and companyName
   1. Firebase: check if doc with key userEmail exists. If so, add an new property: companyName: true
   2. If it doesn't, create a new doc in the Users collection
   3. Firebase checks if a key companyName exists in companies. If it does, it updates the subscriberCount.
   4. If it doesn't, it creates a doc with key companyName and adds the properties:
      1. creationDate
      2. subscriberCount: 1
      3. companyURL: {{URL}}
      4. latestJobOpeningsBlurb: {{HTML}}
      5. latestJobOpenings: [ ]
3. Every week, firebase iterates over all companies and
   1. Calls the Greenhouse API to get latest JobOpenings and saves it to latestJobOpenings: [ ]
   2. Creates an HTML blurb for each new jobOpening since 1 week and saves it to the latestJobOpeningsBlurb section
4. Every week, firebase iterates over all users and
   1. Creates an email template and
   2. For Each companyName gets the latestJobOpeningBlurb
   3. Sends the email
