Is there a trick to activate some party chats?

[Sammun Mak]

I am in chapter 15 and am using a guide to find the last few party chats to get to 100 (PTH). Sometimes it works fine but sometimes I can't get it to trigger at all. Is there something you can do to fix it?

By the way, I am using this guide, https://gamefaqs.gamespot.com/pc/289729-yakuza-like-a-dragon/faqs/78191/party-chat

If anyone has another one that would be great.
