I'm trying to connect a botpress bot via API But I have found several problems, * I have two integrations "webchat" and "webhooks" setted in the studio, but when in list my integretions I get an empty 'array'. (in the network I see that ones) * I'm trying to create a new conversation, but I got the message: "request/body must have required property 'channel'", what is the channel?, if I review the network for example in the studio it is 'channel'. The same for tags, I think the documentation isn't clear about this values. And the same for tags. How can I achive that?
