The blinds (rollers) from IKEA can be controlled in Hue Essentials. They only work on the IKEA Trådfri Gateway.
First you need to connect them within the original IKEA app. After that you can find and control them within Hue Essentials.
You cannot add them to your Philips Hue bridge as this is unsupported. Philips would need to add support for this in order for Hue Essentials to introduce them.
These blinds like FYRTUR and KADRILJ could be added on the deCONZ bridge (ConBee).
