What are Lightning components for update values based on select list in Salesforce?

I would like to create a lightning component for update field based on selected value from "select list" in lwc.

I need this component in "force:lightningQuickAction" - so when user open a example ticket and click the button XYZ component will show (it's alraedy done) and select status - click save then the selected status should be change of current ticket record. What should I do next with it ? What I need to write in controller ?

<aura:component implements="force:lightningQuickAction" >
<lightning:select aura:id = "statusSelect" name="statusChoose" label="Setup new status" required="true" onchange="{! c.onChange }">
<option value="working">Working</option>
<option value="escalated">Escalated</option>
<option value="done">Done</option>
</lightning:select>
<button class="slds-button slds-button--neutral uiButton--default uiButton--brand uiButton" type="button">
<lightning:button variant="brand" label="Save" onclick="{! c.saveClick }" />
</button>
