Installation of SQL Server Express LocalDB 2017

I want to install Microsoft SQL Server LocalDB 2017 on my system. I downloaded SQL Server Express Setup (about 5.1 MB). Then I opened it and chose 'Download Media' option and then chose LocalDB. Then it downloaded SqlLocalDB.msi setup (about 45.9 MB). I ran the setup and installed it on my computer. I don't know what to do next. Can someone help me, please? Output of Running "SqlLocalDb info" command:
