Tooltip Power bi

[letizia]

Hello, I have a tooltip which has value only for some data , so I would like to show it only when data is not null , and I would like to hide it or to reduce his size when data is null. My tooltip is based on a measure which still have a condition on data :

ALERT_text_popup =

VAR resultat = MAX(Alerting[alert_text])

RETURN

    IF(

        ISFILTERED('KPI'[kpi_name]),

        IF(ISBLANK(resultat), "", resultat),

        [ALERT_text_popup_otif]

    )

. As you can see in the picture, I don't want to show an empty tooltip. Thanks in advance
