When your bleeding disc brakes, you are meant to take the pads out, Shimano calipers are supplied with a spacer for this purpose.
If you have contaminated the pads, the simplest option is to bin them, and replace with new. As you have now used the brake, you will also need to decontaminate the rotor, as if you just replace without, you will contaminate the next set.
For resin pads, they work fine for most riders

If you want to try something before throwing them away, heat them in the flame of a propane torch for about 15 seconds each, while reciting the correct spelling of the word "BRAKE" forwards and backwards. Thoroughly clean the rotors before reinstalling the pads; rubbing alcohol is a good start if that's all you have.

You have contaminated the disks a little now too, new (or cleaned) pads alone will possibly not solve the squeal.
When you have to buy new pads you might try ebay.

Traditional brake fluid dissolves easily in water, so I would have just washed them.

"Surely you don't have to remove the pads just to do a brake bleed! Why?"
To prevent them getting contaminated by the bled-out fluid, as the OP has found.

The torch approach has a chance, but no guarantees. Another reason for removing the pads is to fill the system with fluid while the caliper's pistons are fully retracted, so it's possible to fit new pads if/when needed.

Only way to 'thoroughly clean' contaminated brake pads on disc brakes is break out a fresh set.
sintered or resin-organic no different procedure ..
you just messed up and that's part of the cost of learning, sometimes.
