Integrate microsoft teams to post messages in channel

Question

Hello

We are having an application developed using angular where companies can register and can invite other users as well. Now what we want is that if company admin connects with teams from application then other users including admin can post messages in channel means whenever any user post a message then that message should be posted on teams channel as well but other users won't have to connect using teams. Every user will have separate account in application. Is it possible ?

Thanks
