Resolving Draftsman incompatibility with Activerecord

I installed the draftsman gem on a new install of jumpstart pro but it is conflicting with Activerecord.
Is their a workaround?

Bundler could not find compatible versions for gem "activerecord":
In Gemfile:
draftsman was resolved to 0.8.0.dev, which depends on
activerecord (>= 4.2, < 5.3)

rails (~> 6.0.0) was resolved to 6.0.1.rc1, which depends on
  activerecord (= 6.0.1.rc1)

Probably need to find an alternative gem or approach since Draftsman isn't being maintained anymore.
