Development of an external communication protocol with Teams Microsoft Chat

The order involves the development of an external communication protocol with Microsoft Teams, so that it is possible to send information directly to a given user on Microsoft Teams to a specific user instead of an email

So far, we have sent certain data from certain desktop programs by e-mail, now we want to send this data to Teams, specifically to a specific user chat

So we care about the code that we can use in our programs

We have the Full Office 3655 Software Package and maybe Microsoft Power Automate flows (formerly Flow) will be useful for this purpose
