Hi
for list view code in docs reference,

<lightning:listView aura:id="listViewAccounts" objectApiName="CustomObj__c" listName="My_Accounts" rows="5" showActionBar="false" enableInlineEdit="true" showRowLevelActions="false" />

I need some info regarding :listName="My_Accounts"

where does this listNames appear in the setup and how can I create custom ones to reuse in lightning?

Could you please explain in detail.
