Sharing google/yandex/fbPixel targets on onsubmit event?

Question

Facebook

Can you tell me how to use the Facebook pixel event on form submission?
Google/Yandex works like this:

<form class="contacts-form" onsubmit="gtag('event', 'sendform', { 'event_category': 'формы', 'event_action': 'заявка', }); yaCounter65692812.reachGoal('forms_ok'); return true;">

The task is to add an FB pixel event.
If you just insert it like this (fb code in the same line) - it does not work:

<form class="contacts-form" onsubmit="fbq('track', 'Lead'); gtag('event', 'sendform', { 'event_category': 'формы', 'event_action': 'заявка', }); yaCounter65692812.reachGoal('forms_ok'); return true;">

Good afternoon,
no, the method you described does not need to be used.
It is best to set up the activation of these goals through Google Tag Mangar, and not through the onsubmit tag.
Or call an event using js and only then pass it to three different sources.
If everything is hung up on onsubmit, then definitely everything will not be transmitted.
