Normally, dependencies for an attribute can be found using the "Show Dependencies" button when selected, and navigating through the Dependant and Required components sub-grids shown.
In the context of a Custom Workflow Action - a Plugin assembly that has been registered to used in the context of a workflow - this is not the case, despite a number of articles suggesting this is the case when "Show Dependencies" is ran in the Default Solution for the Plugin assembly in the Plugin Assembly entity.
Because of this, the following will need to be added in via FetchXml Builder and ran to retrieve all instances of Workflows which use a Custom Workflow action. The workflow's Name and ID are retrieved in the Results tab.
<fetch distinct="true">
<entity name="workflow">
<attribute name="createdon" />
<attribute name="primaryentity" />
<attribute name="statecode" />
<attribute name="workflowid" />
<attribute name="ownerid" />
<attribute name="type" />
<attribute name="owningbusinessunit" />
<attribute name="name" />
<attribute name="category" />
<attribute name="xaml" />
<filter type="and">
<condition attribute="type" operator="eq" value="1" />
<condition attribute="statecode" operator="eq" value="1" />
<filter type="and">
<condition attribute="rendererobjecttypecode" operator="null" />
<condition attribute="xaml" operator="like" value="%CustomWorkflowActivityName%" />
</filter>
</filter>
<order attribute="primaryentity" />
</entity>
</fetch>
