How are the ssDNA adaptors put onto the discontinuous Mosaic End Tn5 recognition sequences during tagmentation, and how are they made to be discontinuous?

Figure I found so y'all know what I'm referring to

It's my understanding that usually, the Tn5 homodimer carries a continuous strand of transposon DNA flanked by the hyperactive Mosaic End recognition sequences(?) and then inserts this into dsDNA somewhere else. But I don't understand - and no one seems to have the answer - how: 1. they make these discontinuous in the first place, and 2. how they attach this single-stranded adaptor to the transfer strand (how do they know which one is the transfer strand as well???).

I genuinely can't tell if I'm being dense or if literally no one explains this anywhere.
