See trigger status
Status of triggers set through Automation/Triggers can be tracked. Any individual that joins for example, will get a trigger task (if set up). You can see the status of that here.
1. Under Messages section, click Scheduled
By default, all messages that are sent through Dots show up here.
2. To view scheduled Triggers specifically, On the top right, click View Scheduled Triggers. This will filter just the automated triggers, and exclude other messages like Mass DMs, surveys and channel post.
Alternatively, you can also filter this view by clicking the Funnel Icon on Type
And selecting the options you are interested to see
