Hi
In the classic version of salesforce ,I created a custom button that runs an apex class using the javascript function sforce.apex.execute.
This custom button was added in the details salesforce pages like Contact or other Object even in a Custom Object, All is working in the classic version.
My problem is that the custom button does not appear in the Lightning Experience version. It's seems that in this new version , also the javascript functionality has been removed.
Is there an another alternative to call an apex class like it ?
Thank you
