How to add a goal to an event in Yandex Metrics and Google Analytics?

Question

Google Analytics

You need to record how many people click on the Share buttons, order a call, leave a review, log in, register, change the region, etc.
I slightly understood how, you need to add an event identifier for example "clickcallback" to this code

<a href="#" class="call-btn js-callback-call">Заказать звонок</a> а class="call-btn js-callback-call">Заказать звонок</a>

class="call-btn js-callback-call">Заказать звонок</a>

Should I delete this piece of code?
Help how can I be?
