You can control the duration showinfo is active using advancedsettings.xml

Ok. Thanks. That has helped to understand the behaviour.

Now I found the solution now.

In a case someone else need it...

Set a property onload, to get conditional visibility

xml:
<onload>SetProperty(PlayerShowInfo,true,home)</onload>

Used for the Control

aml:
<visible>Player.ShowInfo | String.IsEqual(Window(home).Property(PlayerShowInfo),true) | [Window.IsActive(script-cu-lrclyrics-main.xml) + Player.ShowInfo</visible>

Used a Custom Dialog as workaround

xml:
<?xml version="1.0" encoding="UTF-8"?>

<window type="dialog" id="1195">

    <onload>Action(info)</onload>

    <visible>Player.HasAudio + String.IsEqual(Window(Home).Property(PlayerShowInfo),true) + !Player.ShowInfo</visible>

    <onunload>ClearProperty(PlayerShowInfo,home)</onunload>

    <controls />

</window>
