Looking for "Extract field" feature

[OlivierGre]

The readme file says:

"This plugin automatically supports topics publishing numbers, strings, booleans, and JSON formatted values. Nested object values can be extracted using the Extract Fields transformation."

Where can I find this Extract Fields transformation?

Thanks

Edit your panel, select the "Transform" tab, then press "Add transform"
