Installing an insignia connect smart switch to three black wires and a bundle of three white wires
The group of 3 white wires is your neutral bundle.  Add the white wire from the new switch to it.

The group of two blacks is probably hot and a feed thru, connect both with the black from the switch.

Connect the remaining black (likely your load) to the blue wire.

Ground to ground.  And I bet you have it in the back of the box. (The house looks new enough)
