Is it possible to use `\substack` with `\textnormal` in an `align*` environment?

Question

I am trying to write multiple lines underneath my minimisation problem in an align* environment. This can be achieved by using the command \min_{\substack{x_{j} \\ j=1,...,70}}, which produces the following output

I would like to write minimisation, as opposed to min. However, the command \textnormal{minimise}_{\substack{x_{j} \\ j=1,...,70}} does not produce the required output. How can this be achieved?

The number of left and right curly braces in your expression don't match. — inavda, Nov 17 '20 at 07:31
Off-topic: I would replace j=1,...,70 with j=1,\dots,70 in order to get a proper typographic ellipse. — Mico, Nov 17 '20 at 07:44

From some quick experimentation, using \operatorname* instead of \textnormal seems to do the trick.
