Still appears outside UI is only way. If helpful to others looking at this, how I solved for my situation:

Download the flow as a .zip file

Within the .zip file, navigate “Microsoft.Flow” --> “flows” --> (folder with numbers) --> definition.json
Open the definition as a text file. In this case, I wanted to connect the branch before “Filter array 9”. So I searched for Filter Array 9’s run after property, which is currently after “num_pers_req”

I then modified the run after by adding an additional requirement within the curly braces, by adding the requirement for “Compose_69” to be completed

Save the and update this as the definition.json within your zip folder
In power automate, go to import, and upload the .zip folder

Before importing, you could have also modified the file name within the zip file, or you can do it here. Select config

If you want to replace an existing flow, select the flow to be replaced, click save, and then import

Alternately, select “Create as new” from the dropdown, save, and import

Result:
