Utilizing Automate Flow Data in Power App Dropdown

I am fairly proficient in power automate flows as a whole for bringing data in, triggering to external actions etc. But I am running into an issue when attempting to utilize a flow output data (array) as a dropdown item list within a powerapp.

My current structure is as follows:

--- In Automate Flow

- Power Automate Flow 'GetProjectNames' brings in Smartsheet column contents - Successful

- Compose returned values into array

- Initialize variable 'ProjectList' as array with contents from previous step compose

--- In Power Apps

- Button Trigger Created named 'LoadProjects'

- OnSelect trigger created to run the above flow to refresh project data

- OnSelect=GetProjectNames.Run()

--- Dropdown Created 'ProjectSelect' - This is where I am getting stuck

- Unable to successfully attribute the variable output from the flow 'GetProjectNames' which = 'ProjectList' to = list items within dropdown 'Project Select'

I am unsure best practice for achieving the following:

{dropdown]'ProjectSelect'.Items = {flow}'GetProjectNames' {OutputVariable}'ProjectList
