Deep Link to Form from an email URL in Canvas App

[Darren1372]

Hi, I have a Data Table that is hooked up to an edit form. The data is being populated from a SharePoint List. Data source is called CUOTasks

On the items of the data table I have:

Set(_ItemSelected, true);
Navigate(ReferralTaskFormScreen);EditForm(Form1)

On the form, Item property I have:

If(!IsBlank(DataTable3.Selected.ID) && _ItemSelected=true, LookUp(CUOTasks,ID=DataTable3.Selected.ID),
If(!IsBlank(Param("RecID")), LookUp(CUOTasks,ID=Value(Param("RecID"))), Blank()))

What I need is to somehow generate a link for users to go directly to a record.

I will using power automate to generate the link,

I am not using a gallery.
Can someone point me in the direction of generating a link to the record

Sorry, was being a complete idiot:

Forgot to mention, also has this on App, Start screen:
If(IsBlank(Param("RecID")), MainLandingScreen, ReferralTaskFormScreen)

Then my link  in email (generated by flow):

https://apps.powerapps.com/play/{appId}?tenantId={tenantID}&RecID={sharePointItemId}
The reason data wasn't showing was because I had the form in new mode instead of edit -Doh!
