2 chat different permissions

Hello good afternoon. I need to create on the same page 2 chat rooms, in one that can only write those that have the role of “Author”, and the other that can only write those that have the role of “Author and Subscriber”.

I have these two codes on the wordpress page:

[wise-chat channel="Pizarra01" read_only_for_roles="subscriber"]

[wise-chat channel="ChatUsers01" allow_post_images="0" background_color_chat="#cafcfc" allow_post_links="0" access_roles="{author,editor,administrator,subscriber}"]

Supposedly in the first chat subscribers can read but not write. And in the second, subscribers, admin and authors can read and write.

What happens is that subscribers can read but not write in either. The authors have no problem. Why does this happen? Where is the fault ?.

In the plugin options I have since everyone can access and I have not selected anything in “Read-only For Roles”.

Thank you!
