Question about the disconnect between season 2 and season 3 of Picard

I just finished watching Picard. Philosophy, meaning, and all deep good stuff aside…my question is–what happened to Agnes Jurati/Borg Queen?? Are we to assume she is with another Borg faction that potentially shifted to voluntary assimilation (tho I’m not sure preying on the vulnerable is voluntary - again, deep stuff aside)? I found all of Picard enjoyable and loved season 3. I’m just a bit startled by the disconnect. Thoughts? (Please be kind if this seems silly or discussed already; I’m new to this sub, late in watching Picard, and have not participated in any past discussions.)
