Move htdocs folder in XAMPP 8.0.11-2 on Mac OS Big Sur 11.6

[row3d]

Hi, sorry if this has been answered before but I couldn't find it when I searched. I would like to share the htdocs folder on two machines on my network so I thought I would put all my files in my Dropbox and have the web server on both machines point to /Users/myusername/Dropbox/htdocs to get their files. That way I can develop my web app on both machines and see the results on either web server.

Trouble is that I can't seem to change the location of the htdocs folder on the Mac. I have tried changing some lines in httpd.conf from:

DocumentRoot "/opt/lampp/htdocs"
<Directory "/opt/lampp/htdocs">

to

DocumentRoot "/Users/myusername/Dropbox/htdocs"
<Directory "/Users/myusername/Dropbox/htdocs">

When I select 'Go to Application' in XAMPP, the browser gives me the message 'This site can’t be reached 192.168.64.2 refused to connect.'

Is there something else I need to do or is my approach all wrong? Any help would be greatly appreciated.

My understanding is that to access any directory outside of the installation directory, the httpd process of Xampp must be added to system-preferences-full disk access because OS X has an additional security layer above the unix permissions.
To test, try accessing the folder using the php cli.
