Ratio not starting as default launcher on S10

I just installed Ratio on my S10, it worked but I didn’t get the option to make it my default launcher.
The way to fix it is to go to Apps>Ratio>Default launcher and select Ratio.

i am also using s10 but i cant get the ratio pro to be installed. when i plug my phone in blloc desk it didnt detect my phone (everything is on usb debug.)
