Start-up Emulation Mode

Hello,
I purchased the BM Davinci Resolve Studio and downloaded V19.4. Upon start-up of DRS, a page came up asking what mode I wanted to emulate - DRS, Adobe Premiere Pro, Media Composer and Final Cut. I selected DRS thinking I could change my preference within the program. I haven't found where that preference setting is located. Do I have to reload the software or is there a setting I missed?
Thanks for your help.
