Start xfce-session in background and connect to VNC Viewer

[W5ALC]

I've been trying so get xfce-session to start in the background as in my vnc startup script xfce-session & but when I run this command the script just seems to close and I can't connect to the saved desktop.

I've tried many different iterations like
startxfce4 &
dbus-launch --exit-with-session startxfce4 &
dbus-launch --exit-with-session xfce4-session &

It runs just fine when i remove the &.

And it always seems to just exit the termux session and not allow login through:
the VNC Viewer app.
the VNC VIewer widget
termux-url-opener vnc://ip:port
or
am start -a android.os.BinderProxy@4de5627 -d content://data.AddressBook/entries/866832c4-1935-499f-8166-80d3195c773c -n com.realvnc.viewer.android/.app.DesktopActivity --user 0 &> /dev/null
# this is the am equivalent to clicking my desktop VNC Viewer widget.

All i'm trying to accomplish is running my desktop script and have the saved desktop load instead of the, admittedly ridiculous, 1 extra click.

Here is my desktop script which is located in ~/.shortcuts and executed with termux:widget.
/data/data/com.termux/files/home/.shortcuts/desktop
#!/data/data/com.termux/files/usr/bin/bash
vncserver -kill :1
vncserver :1
export DISPLAY=":1"
#am start -a android.os.BinderProxy@4de5627 -d content://data.AddressBook/entries/866832c4-1935-499f-8166-80d3195c773c -n com.realvnc.viewer.android/.app.DesktopActivity --user 0 &> /dev/null
#am start vnc://127.0.0.1:5901
dbus-launch --exit-with-session startxfce4 &
#sleep 10
#dbus-launch am start -a android.os.BinderProxy@4de5627 -d content://data.AddressBook/entries/866832c4-1935-499f-8166-80d3195c773c -n com.realvnc.viewer.android/.app.DesktopActivity --user 0 &> /dev/null
#am start -a android.os.BinderProxy@4de5627 -d content://data.AddressBook/entries/866832c4-1935-499f-8166-80d3195c773c -n com.realvnc.viewer.android/.app.DesktopActivity

Note : the commented lines are different things i've tried

I can gather any other information needed to help solve this odd problem. It shouldn't behave this way, right?

logcat -d # this is everything from when the Termux widget script runs until it quits.
