I include a Visualforce in the lightning record page of Account and I would like to open new subtab in the same service console with a lightning component.
Is it possible to do that? If so, how?
I just came up with a Summer 18 feature which allows opening lightning component as a new tab.
You can also consider the subtab from the VF page using the JS "sforce.console.openSubtab" . But it will only open the URL so you may need to embed your custom lightning component to a VF page and then use the VF URL in the above function.
