How to split kitchen cold water outlet into three (faucet, water filter, fridge?

I have one copper pipe with one shut-off valve underneath my kitchen sink.
How can I split it into three?
- water filter (comes with a 1/4" brass tee: https://cdn.aquasana.com/assets/AQ-5...00_Install.pdf)
- fridge icemaker
- main faucet

I would first split it in two: main faucet and water filter. Then I'd split the water filter output in two: drinking water spigot and fridge. Then your ice will also be filtered.

Interesting idea. My fridge does have a filter as well. Not sure whether I can bypass the fridge filter. But like the idea here.

Install a tee onto your copper pipe, a short length of pipe, then a single inline quarter turn shutoff straight up to the sink and on the right or left side of the tee, a short length of pipe then a quarter turn 90 degree tee shutoff. Assuming you have a separate drinking water spigot on your sink.

If the fridge has its own filter, no need to pass water through the under-sink filter.

Assuming the tee needs to be soldered?

and then on filter side, ideally a T that splits into 2x 1/4"?
Are there such T's with 2x 1/4 outs?

or

it seems most of those valves split either to two 3/8 or one 1/4 and one 3/8
