SPFx multiple application extensions

[KJS]

I have a SPFx solution when i try to deploy mulitple app ext in the same solution as a part of same package. after the package is deployed only default extension is activated and not the other one. 

I have added a new custom action in the element.xml file but still no luck, Can anyone tell what i am missing 

Appreciate any help

Can you please tell me how you add multiple app in the same solution ?

And your version of SPFX ?

Add the entries in the elements manifest file, and if you are considering clientsideinstance.xml, made another entry as well. Do gulp clean, bundle and package the solution

I'm in the same boat. Were you able to fix this issue?
