I want to modify the Send Email Global action and add some custom fields to the layout which is not possible in the standard Global Action. Hence I am trying to create a Lightning Component and add it to the Activities Layout as shown in the picture below.
The Lightning Cmp implements="force:lightningQuickAction" and I have added it to the Pagelayout under 'Salesforce Mobile and Lightning Experience Actions', but the cmp is only displayed with other Action. What should I configure to add the Ltng cmp under Activity Layout?
