Starting and stopping the Drive activity notifications even if they are already started or stopped should show correct error.

[AayushChaudhary0001]

This issue was found during the testing of this plugin.

For start activity slash command:
If the user runs the slash command "/drive notifications start" even if the notifications were already started (enabled), the user receives the message that the notifications have been started, instead, it should be that they are already enabled. This is a suggestion if we can work on it.

For stop activity slash command:
If the user runs the slash command "/drive notifications stop" even if the notifications were already stopped (disabled), the user should receive a message that they are already stopped, or there should be a consistency with the case above. But the user receives a message of something went wrong and contact your org admin.
