Hi @conghc,
Thank you for your responses and feedback.
Yes, this should not be an issue. The only thing I will mention is that the application name is not very informative and could be a source of confusion in the future. With that, you could consider creating a new machine-to-machine application with the desired application name.
Please see this thread for an explanation on the “(Test Application)” application name.
Hoped this helps!
Thank you.
