Suitable speakers for the ReSpeaker 2-Mics Pi HAT?

I just got the ReSpeaker 2-Mics Pi HAT and, to my ignorance, bought along with it a 1W speaker with a PicoBlade molex connector, whereas the HAT has a JST output.

Is there any way for the JST output to be adapted into the molex connector? Or should I buy a speaker with a JST connector?
