@tapaswenipathak I think we should use this:
https://myst-parser.readthedocs.io/en/latest/syntax/optional.html#linkify

And probably some other markdown extensions

[tapaswenipathak]

this should do: c4c8128

I don't understand - what is the advantage of using linkify?

[jpfeuffer]

I think just that you don't need to do [url](url)

@greengypsy can we close this?
