Hi,
I'm following https://github.com/basa-casa/hugo-admin#installation but I facing a problem;

I have hugo v0.126.1+extended and there is no config.toml/.yml/.json file in the folder. There is just hugo.toml and when i add these below lines

[module]
    [[module.imports]]
        path = "github.com/basa-casa/hugo-scms-admin"

into this file and run hugo mod vendor command i get this error:

Error: failed to load modules: module "github.com/basa-casa/hugo-scms-admin" not found in "..../hugo/quickstart/themes/github.com/basa-casa/hugo-scms-admin"; either add it as a Hugo Module or store it in "..../hugo/quickstart/themes".: module does not exist

what did i do wrong? 🙄
