How to we see Record when we Hover on a lookup field in Salesforce Lightning

Do you know how to see Record when we Hover on a lookup field in Salesforce Lightning?
Requirement –
I have an Object name “Car Brand” – (Master Object) and this object has the Lookup of “Car Model” – (Child Object). And I want to see the ‘Car Model’ object’s fields when I’m on the ‘Car Brand’ object using hover.

When I open a record and go to its Related List and hover the mouse on the lookup field then I want to see some fields of the Related object.

Let’s Come with Me and configure it because it’s Easy and Understandable.

Step 1 – Go to Setup >> Object Manager

Step 2 – Click on Object Manager >> (Type your object name which you want to see the field on the time of hover) >> Click on your object name.

Step 3 – Click on the Compact Layout >> New (Button).

Step 4 – Insert the Label and Choose the fields which you want to see in hover time.

Step 5 – Click on the ‘Compact Layout Assignment’ then ‘Edit Assignment’ and choose your own created Compact Layout as ‘Primary Compact Layout’ and Save.

Now, Open your Record and see the fields which you want to show on Hover Time.

Finally, we had done it but now come to the Remember Things.  

1 - Only 4 fields we can see on the Hover Time.

      2 - Always when you choose fields, keep important fields at the top.
