From underneath, with a very small flat file ( the 4-5" gunsmith file kits are cheap & invaluable) run a light score across 1 of the 6 'hex' corners on the inner tie rod. This is 17mm, and you have now made one of two reference points! Jump across the 22mm locknut to the threaded rod of the outer tie rod half ... and drag the file lengthwise across the threads exactly in line with the score on the hex point.
These two 'shiny' marks reference the correct toe-in ... and allow you to return there even if one screws up.
With flat wrenches, counter hold the 17mm and loosen the 22mm nut. To adjust, one turns the inner 17mm hex in reference to the marked outer tie rod. The outer rod has a thread pitch of 1.5mm and 1/6 of a turn equates to ~10mm movement on the circumference of the steering wheel provided one side is lengthened exactly the same amount the opposing side is shortened!!
To rotate the steering wheel position clockwise, the left tie rod must be shortened .... and the right lengthened.

Yeah, it's 'wordy' .... but easy to mess up if imprecise - so excuse the prose. As is evident, a small change has a reasonably large effect on the wheel .... so the caution is that any small imbalance in the adjustments left to right can also alter the total toe-in setting.
Be careful in the measurements - and this works.
