Custom Button to update Field on Account object

Question

I have a custom button that's supposed to update a field on the Account Object. I made this work via Javascript process, but the problem is this Custom button won't show up under custom links in Account object when in Lighting, it only shows up if I am using Classic.

On the warning it says Java script behavior isn't supported in lighting, what else can I do to update a field on the Account object?

Here is the code I have thas currently working but it's Javascript.

{!REQUIRESCRIPT("/soap/ajax/19.0/connection.js")}
var accnt = new sforce.SObject("Account");
accnt.Id = '{!Account.Id}';
accnt.wow= 'True';

var result = sforce.connection.update([accnt]);
if(result[0].getBoolean("success"))
{
alert('Running process...');
window.location.reaload();
}
else 
{
alert('Error : '+result);

}

How can I archive this without using the Java Script

So Javascript buttons don't work in Lightning experience. So for your usecase, first you need to create an object action (aka quick action) by creating a button in Account object where you need to select "Action Type" as "Update a Record". After that, modify the Publisher Actions Layout by dragging the newly created action to the Publisher Actions section.

You can check the link below for more information and perform the 1st and 3rd steps to replicate the scenario with your needs:
