¿Advanced? Query

I have this database:

I want to query:

> people
    > name
    > assistMeeting
        > firstSpeaker
             > name
        > secondSpeaker
             > name

Is possible to have this query nested?

I tried this query:

image729×470 14.3 KB

Output:

image467×691 9.63 KB

Still need the nested info for the speakers, like name for example.

P.D.: Clarify that one person only can assist to 1 meeting (they are at the same hour)
