How to set SYNO_TOTP_SECRET

[MrGibbage]

I am trying to deploy my cert, using the instructions here:
https://github.com/acmesh-official/acme.sh/wiki/Synology-NAS-Guide

When I run the command
./acme.sh --deploy --home . -d "$CERT_DOMAIN" --deploy-hook synology_dsm

I get an error.
root@homeassistant:/usr/local/share/acme.sh# ./acme.sh --deploy --insecure --home . -d "$CERT_DOMAIN" --deploy-hook synology_dsm

[Fri 11 Nov 2022 10:46:28 AM EST] Deploy error.

I have the following environement variables set
root@homeassistant:/usr/local/share/acme.sh# set|grep SYNO
SYNO_Certificate=
SYNO_Create=1
SYNO_DID=copied from the cookie in Chrome
SYNO_Host=192.168.0.2
SYNO_Hostname=192.168.0.2
SYNO_Password=secret password
SYNO_Port=5000
SYNO_Scheme=http
SYNO_TOTP_SECRET=
SYNO_Username=myusername

I do have 2FA enabled. What do I set SYNO_TOTP_SECRET to? I tried using the SYNO app on my phone and got the time-based OTP number and then quickly running the command, but I still get the same error. I am also confused if I should be using port 5000 or 5001 and http or https. In my browser, if I go to http://192.168.0.2:5000 it automatically changes it to https://192.168.0.2:5001
