Hi @JKunal
Sure, Let me give a small example to get understand things better
Let's say i have window liks this

Now my requirement is to click on close button which is highlighted below

I am using move mouse to text action to move the mouse to close button and then click it.
The way i tried is using the text Insert file with reference to Insert file text made the activity to move offset from the mouse so that it clicks on the close button. After lot of tryouts, finally got the exact coordinate with respect to text by which we need to click text see below

Look at advanced properties below

Flow will move mouse 985 pixels to the right of Insert file tex to click the close button.
By using the same approach you have to design the flow which clicks the checkbox based on input text .
Hope this helps !
