More globally, what developer user account should we use in our company to create the app? If everything is under my account, it would be a problem when there are some updates to do and someone else from my team has to do it.
Normally, each application is owned by one account. The settings required for an integration/bot etc. will not change that often, so in most cases it would be sufficiant to wait until the owner is back in the office for instance.
