Creation of an intern messagery inside webflow site

Hi everyone ! I am on a project with a company which sells for their subscribers the ability to ask 5 questions to their expert team. In order to fullfill this, they need to implement a private messagery (with the only possibility to contact the expert team and not another member) in the webflow site (on the logged member space). I don’t know if it is possibile and if yes, I don’t know how to makes it works well as the team will need another platform to answer the question asked and then, the answer displayed on the private messagery of the member.

Do you have any idea ? I figured that it may be possible using Zappier+ something like Airtable but I am not sure and I don’t know how to do that.

PS : members are actually managed via memberstack.

Thank you a lot !

Benjamin
