As you could have imagined those are multiple fetched layers. Actually I had 6 of them for 6 possible scenarios and just replace the right base64 code in.

Here’s one for the 6th image, which fits with the Pros & Conference meeting you see in the screenshot.
{I1} to {I5} are base64 codes, {C} is the “plus” count (that is greater than 5).
