Installation / set-up required for non-acdemic resume?

[brshallo]

I am not able to run the example for "Steve's Non-Academic Resume Template." What are the required steps for set-up? I'm running into issues with the fonts, specifically this error:

! Package fontspec Error: The font "Fira Sans" cannot be found.

To get here I opened an Rstudio Cloud instance:

Sys.info()
#>                                               sysname 
#>                                               "Linux" 
#>                                               release 
#>                                      "5.4.0-1037-aws" 
#>                                               version

#>                                               machine 
#>                                              "x86_64" 
#>                                                 login 
#>                                             "unknown" 
#>                                                  user 
#>                                        "rstudio-user" 
#>                                        effective_user 
#>                                        "rstudio-user"

Then ran:

install.packages("stevetemplates")

tinytex::install_tinytex()
tinytex::tlmgr_install("cochineal")

Then clicked "knit" (resulting in error mentioned above).

I'd also tried tinytex::tlmgr_install("fira") and downloading + installing Fira Sans font but still got stuck at the above error message. (Note that just setting sansfont: cochineal works fine though).
