How to link to a process dashboard from process backed record

I have a process backed record type with grid style record list.  Building an interface and wanted to provide a link from the first column so it can take the user to the process dashboard. How this can be achieved? I tried using the below in summary view.

rule!formattedLinkToDashboard(rf!,""). It doesn't seem to work and returns a blank page.

Also, in interface, this is what  i have.

label: "PR Number",
field: "MilestoneSchedule.ReqNumber",
data: index(local!, "ReqNumber", null),
links: a!forEach(
items: local!datasubset,
expression: a!recordLink(
label: "Go to record view",
identifier: fv!identifier,
dashboard: "summary"
