Good day,
According to Sales channel creation guideline (https://shopify.dev/marketplaces/developer-tools/channels-ui) we have to use @Shopify_77 /channels-ui library. This version is not compatible with latest version of App-bridge and fails to install in the app. Furthermore, github with this library is not available anymore, so, I can’t fork it and resolve compatibility issues.
From the other side, previous version of App bridge fails to run on shopify platform (JS error is the same as in https://github.com/Shopify/shopify-app-bridge/issues/145).
Do you have any advice, how to develop sales channel app now to make it available for listing?
