What is the Request Block

What does the request block do, like what is its function

btw i mean the one in the control category

request [] works with when I recieve [] blocks and report blocks.

Basically request [] sends a message and you use report [] to send a message back, and finally request [] reports all the values sent back.

wait what there’s another?

There are two in the MQTT library:
MQTT request 1
MQTT request 2

oh, of course. I didn’t really think of those when I was searching for the request block.

i dont mean those by the way
