Hello Jana,
The documentation has a guide on how to set up multimedia recording. You need to save a .php file with the content from the code block under “Server setup” and upload it to your webserver. There exist commercial services to obtain webserver space (eg. DreamHost) and some institutions (eg. universities) also provide some webserver space to their members. Google Drive cannot be used to run PHP scripts (it’s a cloud service, not a webserver)
Alternatively, you can send the recordings to an S3 bucket, but the setup is somewhat more complicated in this case
Let me know if you have questions,
Jeremy
