Hellos Experts,
I am building a PowerApps for our HRs to request trip letters. The application is connected to a SharePoint list where I have one person column named "Employee". The user will need to enter in the PowerApps and submit a form to request a letter.
In the field "Employee", each HR will search and select the name of the employee who will go on the trip. I am trying to populate (based on the employee selected) an ID we use in the company, which is not in the options populated in PowerApps. This is an attribute created by my company.
I already now the Azure AD attribute name of this ID, however, I do not know how to get this attribute from PowerApps.
I know how to get this attribute using Flow Automate (see below image), by selecting 1)User: Employees Claim and 2)Select field: the Azure AD attribute. However, this work only once I have saved the information into SharePoint.
In my case, I need to get the attribute at the time the employee is filling the form, which will be before submitting it into SharePoint.

I was wondering if it was possible to get this information using the correct connector in PowerApps or if it was possible to trigger a Flow-based if the "Employee" field from PowerApps has information.
Thank you in advance! I really appreciate your support 🙂
