Echannel is well worth the effort because it saves you a boatload of time on each entry and exit.

You can only apply for it upon entry. Bring all documents you might need with you. I believe normal visas are now okay, but they must be valid for at least six months.

For your first post-Covid entry, plan on 90 minutes. The fingerprinting drill is a serious time suck. But, the staff is quite friendly, and they will let you into the country.
