Opening multiple dialogs

[FPORTELLA5]

When clicking a button on a card, it opens several dialogs on other cards, when closing a dialog it closes all the others, how to fix it to open only one dialog. My code:

<p-button (onClick)="showDialogMaisInformacoes ('')"
icon="pi pi-plus"
pTooltip="Mais Informações" tooltipPosition="bottom" placeholder="Bottom"
styleClass="border-primary-500 border-1 border-solid border-round cursor-pointer transition-all
transition-duration-200 hover:bg-primary-600 hover:border-primary-600 active:bg-primary-700
active:border-primary-700 border-circle"/>
<p-dialog
[(visible)]="visibleDialogMaisInformacoes"
[breakpoints]="{ '1199px': '75vw', '575px': '90vw' }"
[maximizable]="true"
[modal]="false"
[style]="{ width: '50rem' }"
class="p-col p-md-6 p-lg-4 text-left p-3 -mt-3 text-sm" header="Mais Informações">

<div class="p-col p-md-6 p-lg-4 text-left p-3 -mt-3 text-sm" *ngIf="doc.cdObraAbramus != null">
Abramus:
{{ doc.cdObraAbramus }}

<div class="p-col p-md-6 p-lg-4 text-left p-3 -mt-3 text-sm" *ngIf="doc.cdObraEcad != null">
Ecad:
{{ doc.cdObraEcad }}

                </div>
                <div class="p-col p-md-6 p-lg-4 text-left p-3 -mt-3 text-sm" *ngIf="doc.sitCadastral != null">
                    <label class="text-left font-bold  text-base">Situação:</label>
                    <span type="text" class="p-2 line-height-3">{{ doc.sitCadastral }}</span>
                </div>
                <div class="p-col p-md-6 p-lg-4 text-left p-3 -mt-3 text-sm" *ngIf="doc.dtAtualizacao != null">
                    <label class="text-left font-bold text-base">Atualização:</label>
                    <span type="text" class="p-2 line-height-3">{{ doc.dtAtualizacao | date:'dd/MM/yyyy' }}</span>
                </div>
            </div>
        </p-card>
    </p-dialog>
