After searching everywhere, and ordering 3 parts that don't work, I've decided to ask for some help.

I have a laundry room sink faucet that I believe is 3/4 garden hose thread with a male end. I've been trying to find a converter to 55/64 (I think?) so I can connect a standard diverter for use with a hose sprayer or similar. I cannot find this part anywhere!?

Can anyone steer me in the right direction?

Here are some photos of my setup:

For the diverter, I am just looking to add something like this in whatever size configuration I can make work:

Thank you for any help!!
