I6 with angular : swiper instead of ion-slides (I7 deprecated) : try to add slide dynamically

ion-slide deprecated in I7.
So i replace ion-slldes with swiper in I6/Angular
But now i would like to add a slide dynamically

When you read Swiper API

Manipulation module adds useful Swiper methods to manipulate slides. It makes sense to use it only with Swiper Core version, not intended to be uses with Swiper Angular, React, Svelte or Vue.

Any idea ?
