Grouping Power Query Column

I am working on a scheduling calender. I can get it to work with single events per day, but this part is throwing me for a loop. I cannot seem to group, or combine the events to singular cells with matching dates. Below is my query:

What I am hoping to achieve is like the following:

Can anyone give me some advice for this? I've tried group columns, and multiple formulas using Text.Combine, but I cannot seem to get anything to work properly.

THANKS!
