Slack bot linking to other channels in the web application

Question

So I am working on a slack bot that displays a link to another channel when a command is given. Everything works in the native application (desktop / mobile) however it does not work in the web. I are using the slack:// format for linking to the channel and based on the documentation:

https://api.slack.com/reference/deep-linking

It seems that format only works in the native app, not the web app. The same documentation makes reference to the https://slack.com/app_redirect?channel=C0VD1QBZB&team=DN4DC67TG2 which does work for the web application (even if the UX is not as good as it will open that in a new tab instead of the same window) but that also opens the channel in the web from the native client application which I don't want so I have 2 questions:

1. Is there a way to know if the context of a slack bot message (like the one that happen with the user issues the command that display this link) came from a native application or web application that was I either the correct link format based on where the user is working from?
2. Is their a way to link to another channel from the web without it loading into another tab?
