There are two automations in this document. One that will post your tweets, and another that will retweet your tweets if you have that setting on. You must navigate to the settings and set these automations to run as yourself.
Navigate to the automations with the settings cog in the right hand to corner of this doc. Then, select each of the two automations in the doc and on the very bottom there is a little “Take actions as automation bot” setting. Click on this and change it to run as yourself.
