This is example of the Microdata which is attached in every email I send out to a customer:
<div itemscope itemtype="http://schema.org/FoodEstablishmentReservation">
<meta itemprop="reservationNumber" content="123456"/>
<link itemprop="reservationStatus" href="http://schema.org/Confirmed"/>
<div itemprop="underName" itemscope itemtype="http://schema.org/Person">
<meta itemprop="name" content="Test Tester"/>
<meta itemprop="email" content="test@example.org"/>
</div>
<div itemprop="reservationFor" itemscope itemtype="http://schema.org/FoodEstablishment">
<meta itemprop="name" content="My Venue" />
<meta itemprop="image" content="https://example.org/venues/images/1.jpg" />
<div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
<meta itemprop="streetAddress" content="123, My address, City, Country" />
<meta itemprop="addressLocality" content="City" />
<meta itemprop="addressRegion" content="City" />
<meta itemprop="addressCountry" content="Country" />
<meta itemprop="postalCode" content="12345" />
</div>
</div>
<meta itemprop="startTime" content="2021-10-12T17:00:00+02:00"/>
<meta itemprop="bookingTime" content="2021-10-05T00:08:00+02:00"/>
<meta itemprop="modifiedTime" content="2021-10-05T00:08:00+02:00"/>
<meta itemprop="partySize" content="2"/>
</div>
This validates in their tester, but it still doesn't show up opening the email. Is there anything that stands out being wrong?

After reading the documentation extensively I finally found a page in their documentation explaining the entire process. We completed every step and our emails are now accepted by Google and now properly creates the visualisation when someone opens our email in GMail.
The documentation of all things required can be found here: https://developers.google.com/gmail/markup/registering-with-google
The most important part is that you need to complete the step:
- Fill out the registration form and we will get back to you.
After properly filling out the form, you will have to wait ca 48 hours before a representative from Google will contact you.
