Zoho Project chat - archive, delete, disable

Zoho Project chat - archive, delete, disable

 Hi everyone!

I just started to use Zoho Project (Standard Version). I d like to ask some questions about the chat function:

1) Is it possible to deactivate it, after activation and usage? (for example, I want to use it in another project.) Or do I have to delete the complete project? (or buy an upgrade?)

2) Is there a way to delete archived chat transcripts?

3) The project name is the main chat topic (not archivable). Is there a possibility of cleaning the content?

Thanks in advance
