fstab entry to automate mounting B2 Backblaze bucket to local mountpoint

I maintain a ubuntu 20.04 LTS headless server and I can manually mount the B2 bucket using fuse s3fs for backup. How to add a line to fstab to automatically mount the B2 bucket at powerup? I know that altering fstab can be tricky. The mount script I have obtained from Backblaze [FAQ](https://help.backblaze.com/hc/en-us/articles/360047773653-Using-S3FS-with-B2) : > sudo s3fs \ > mybucket \ > /path/to/mountpoint \ > -o passwd_file=/etc/passwd-s3fs \ > -o url=https://s3.your-region.backblazeb2.com
