How would you prepare for a language exchange meetup?

I have the opportunity to go to a local language exchange meetup twice a month. I would like to participate and make the most of these two two-hour meetups.

How would you prepare for something like this? Im around n5 level and am already doing Anki, bunpro, and wanikani(which isn’t the most helpful in this speaking context). I have a tutor who helps me once a week which has been very helpful. We mainly focus on doing e->j and j->e translations but my speaking( and listening) skills are still very low. I know I’m going to have to just jump into the deep end here but if you’ve done something like this before I’d like to hear your advice or experiences.

Thanks!
