@HannaTrotsenko why do we need it? A white-label partner can clone this repo and make all the modifications it in. Then he would use his own copy in his tenant.

@drobiazko this is suggestion from @pnedelko
Maybe we should just describe in documentation how it can be specified for each single customer

[drobiazko]

Sure, we can. However this is another issue.

[pnedelko]

@drobiazko do you remember that this repo is mentioned here? How are we gonna white label it?

[drobiazko]

@pnedelko We need to provide an env var for that in frontend
