Using UVLO functionality on LT8315 Flyback Converter

UVLO=Under voltage Lock out

I have a circuit made in LTspice which is straight from the datasheet of the LT8315 flyback converter. It takes an input voltage range of 20V-450V and outputs a constant output voltage of 12V. Currently, the UVLO pin is simply connected to bias as shown in the image below:

I am trying to use the UVLO pin such that UVLO functionality occurs when the input voltage is less than 60V. The datasheet says to connect the UVLO pin to a resistor divider if UVLO functionality is desired.

According to the datasheet, the chip will not operate if the voltage at the UVLO pin is less than or equal to 1.22V. So, when the input voltage is exactly 60V, I want a resistor divider such that the voltage at the UVLO pin is exactly 1.22V. I have done the calculations for that below:

Vout=(R2/(R1+R2))Vin 1.22=(R2/(R2+R1))60

0.00203333=(R2/R2+R1)

Let R2=100ohms

Then, R1=(0.998/0.002)R2 R1=(0.998/0.002)(100ohms)=49.990kohms

Essentially, my question is how exactly and where exactly would I connect the resistor divider so that I can accomplish my goal?

I am sorry if this is a bit of a dumb question but I'm figuring this out as I go. If anyone has experience with flyback converter circuit design, I would appreciate your advice as I am a bit confused on how exactly to connect the resistors.

Thank you!

Also, here is a download link to the LTspice schematic. It's just below. Let me know if it does not work for you.

$$\dfrac{V_{out}}{V_{in}}=\dfrac{1.22}{60}=k$$ $$\dfrac{R_2}{R_1+R_2}=k$$ $$R_2=R_2\cdot k +R_1\cdot k$$ $$\dfrac{R_2(1-k)}{k}=R_1$$ $$R_1(R_2=100\Omega)\approx 4,8k\Omega$$
