Creating a Flow
Navigate to flow.microsoft.com and select templates in the top navigation bar. For example, type in “Slack” and then select the search icon.
Now, only Slack-related templates will show up. Select Send a message on Slack when my manager emails me.
Select Use this template.
Sign in using your Office365 credentials. This flow will appear.
You can then customize your flow to fit what you require it to do.
