Hi Anshi,

first you need to create a Ligtning component that will use SQOL and fetach contact with test 

Select id,name from contact where name Like 'Test%'

<aura:component controller="ContactDetail" implements='force:hasRecordId'>
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>



<!--use boolean attribute for Store true/false value,
    make default to "false" so modal box are not display on the load of component. 
    --> 
    <aura:attribute name="isOpen" type="boolean" default="false"/>
    
    <!--Use "slds-m-around_xx-large" class to add standard X-Large padding to the component--> 
    <div class="slds-m-around_xx-large">
        
        <lightning:button variant="brand"
                          label="Contact"
                          title="Contact"
                          onclick="{! c.openModel }" />
        <!--Use aura:if tag to display Model Box, on the bese of conditions. [isOpen boolean attribute] -->   
        <aura:if isTrue="{!v.isOpen}">
            
            <!--###### MODAL BOX Start######--> 
            <section role="dialog" tabindex="-1" aria-labelledby="modal-heading-01" aria-modal="true" aria-describedby="modal-content-id-1" class="slds-modal slds-fade-in-open">
