How to prevent a modal from closing when clicked outside the modal in Angular?

Question

I've read several Q&A's on this issue and all the suggestions are for a very simple solution: add

in the HTML tag of the button responsible for opening the modal.

data-backdrop="static" data-keyboard="false"

For me, this button is:

<button type="button" class="btn btn-primary btn-danger m-2" data-bs-toggle="modal" data-bs-target="#exampleModal" data-backdrop="static" data-keyboard="false" (click)="onDelete(object.id)"><fa-icon [icon]="faTrash"></fa-icon></button>

The complete modal box is:

<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <!-- <h5 class="modal-title text-center" id="exampleModalLabel">Biztosan törölni akarod?</h5> -->
        <button type="button" #closeButton class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        <h5 class="modal-title text-center" id="exampleModalLabel">Biztosan törölni akarod?</h5>
        <p class="text-center">A törlés megerősítésével az adatbázisból is eltávolításra kerül a rekord.</p>
      </div>
      <div class="modal-footer justify-content-center">
        <button type="button" class="btn btn-danger" data-bs-dismiss="modal" (click)="confirmDelete()">Törlés</button>
        <button type="button" class="btn btn-primary" data-bs-dismiss="modal" (click)="declineDelete()">Visszavonás</button>
      </div>
    </div>
  </div>
</div>

But every time I press ESC or click outside the modal, it closes. I also tried managing it from TS, using @ViewChild modal (referencing the modal's DOM div), and a dialog: MatDialog property, and then after pressing Delete In the onDelete() method called when pressing the button, I simply entered this.modal.open(dialog, { disableClose: true });, but nothing kick in. I'd prefer to just solve it from HTML. Is there anything I'm missing? (I'm using angular 14.1.1 and bootstrap v5)

Backdrop must be set to static so that the modal does not close when clicking outside it, but it is set to data-bs-backdrop="static" instead of data-backdrop ="static"

<!-- 触发模态框的按钮 -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#staticBackdrop">
  启动静态背景模态框
</button>

<!-- 模态框 -->
<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="staticBackdropLabel">模态框标题</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="关闭"></button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">关闭</button>
        <button type="button" class="btn btn-primary">了解</button>
      </div>
