How do i make a custom button for New Task and New Event? I want to display in Salesforce Mobile and Lightning Experience Actions

I want the button so the user gets the full dialog box, not the LEX small window in Actvities page tab. Was told by SF support can only be done through coding and to ask developer community.
Hi Mia,
We have custom button for New Task and New Event. Please let me what is your requirement and we can directly connect on my gmail for demo of our lightning components.
