Hi, and welcome to the community!
There isn’t a fixed timeline for add-on reviews. We manually review new submissions to keep users safe, and we have been seeing a large influx of add-ons lately, so wait times can vary. We recently made a public post addressing that issue.
One thing that genuinely helps speed things up: include your source code with the submission. It makes it much easier for the reviewer to verify everything quickly.
In the meantime, your add-on is in the queue and will be reviewed. If it has been an unusually long time, feel free to reply here with your add-on ID and I will take a look.
Thank you for your patience.
