There are 2 usernames for remoteDesktop. The bot was created on A user. How to run it on B user?

There are 2 usernames, lets say A and B.

The bot was created on A user, and it runs perfect.

When the user changes to B user, and run it, it runs on A user, but it is expected to run on B user.

This is a problem my friend is facing, and i couldnt find a solution since i didnt come across with this before.

What should we do?
