Do not forget that that gives Bot Owner status according to DBM( as in access to anything set as Bot Owner Only )
Insert the desired owner's Discord ID, It MUST be the discord id, not the name of the user (Right click -> Copy ID on the users name with developer mode enabled) Once you click the + to add the id, you may close the extension and restart your bot.
Failure to restart your bot will result in the the user to not have Bot Owner Only status
