If you want to test the exported project not only on localhost (for example on your phone), then you'll need to run an HTTPS file server with COOP and COEP (Exporting for the Web). Also don't forget to activate extension support:
To run HTTPS, you'll need an SSL key and certificate, which can be generated using one of the scripts below (openssl generate ssl key&cert file.*) or you can use an existing certificate that is distributed with this archive.
You need Python 3 installed and its path must be added to the environment variables so that it can be run from anywhere. Python can be pre-installed on your Linux.
