Any advice on duplicating this?
I can get the one tie in there, but not the multiple slurs
“Out of the box,” I can get the following by click/CTRL-clicking individual note heads for the slurs. So far I hit F to flip the bottom slur and used the Properties panel to flip the tie. To move closer to your example, I would expect to use the Engrave Mode to adjust the remaining slurs, particularly the one from A to G (if you read this in treble clef).
Select the first note in each pair, then Cmd/Ctrl+select the second note in each pair. Then hit S.
Repeat three times.
Hit F with the bottom slur selected to flip it under, then go into Engrave mode and do some frustrating dragging.
