KDE Calligra Flow - not in pamac - how to install

I wish to try Calligra Flow to draw flowcharts.
RE: https://www.calligra.org/flow/

However, don't see in pamac
How to install it?

I think the Flow part of calligra has been unmaintained for a while, and therefore was dropped for the time being by upstream.

See Karbon

Karbon it's to create vector graphics,
Flow is intend to produce flowcharts in flowchart file format, such as .VSDX (Visio 2013)
