Pass data from TabsPage to ChildTab

Hello to all.
I am developing an app that has a 4 tabs
This is the html page

<ion-tabs>

  <ion-tab-bar slot="bottom">

    <ion-tab-button tab="profilo">
      <ion-icon name="person-sharp"></ion-icon>
      <ion-label>Profilo</ion-label>
    </ion-tab-button>

    <ion-tab-button tab="chat">
      <ion-icon name="chatbubble-sharp"></ion-icon>
      <ion-label>Chat</ion-label>
    </ion-tab-button>

    <ion-tab-button tab="random">
      <ion-icon name="search-sharp"></ion-icon>
      <ion-label>Trova</ion-label>
    </ion-tab-button>

    <ion-tab-button tab="dintorni">
      <ion-icon name="compass"></ion-icon>
      <ion-label>Scopri</ion-label>
    </ion-tab-button>
  </ion-tab-bar>

</ion-tabs>

I need to send a request to the server every 5 seconds to get data.
I want to put this call in the main tab (TabsPage) and then pass the data obtained in the TabChat.
Is it possible to do this or do I have to insert the call to the server in each tab?

So the question is this: how do I pass a data from the tabPage to the tabChat?
