Converting a detail page button to Lightning

I am trying to convert a detail page button which sets the default value through the Link URL to the lightning. 

User-added image

In the lightning it doesnt work setting the default values (in my other post it was said that this feature will be available in Lightning in the Spring'20 release and suggested the work around can be Quick Actions. I tried the quick Actions but the issue is I cannot set the default values for the lookup fields

Is there any other way I can approach this using VisualForce Page/ Lightning Component. I am new to Salesforce and Any help is greatly appreciated.
