Iron particles around a magnet

There are some iron particles on a board. We pass a current carrying wire through that board and the particles form circles. Show these circles if input given is the position of the wire.
Consider the board to be a grid of size 7x7 (fixed)
No extra white spaces are allowed.
Input can be 0-indexed or 1-indexed. (0-indexed in examples)
Examples
input:3,3 # 'X' is wire here but can be shown by anything other than '/|-'
output:
/-----
|/---|
||/-||
|||X|||
||-/||
|---/|
-----/
input:1,2
output:
|/-|||
||X||||
|-/|||

Can the function output a 7x7 matrix with the characters or we need to print it on the console ?

ＧL⁷-↙⁶X‖Ｂ↘¬‖Ｊ±Ｎ±ＮＴ⁷¦⁷
Try it online! Takes 0-indexed column and row as input. Explanation:
ＧL⁷-
Draw a triangle of -s.
↙⁶
Draw a line along the hypotenuse. (This is the wrong way around but we'll fix that later.)
X
Draw the X that shows the position of the wire. (Any other ASCII character could be used here of course.) This completes one eighth of the drawing.
‖Ｂ↘¬
Reflect three times (¬ = left + down) while transforming characters to almost complete the diagram.
‖
Reflect without transforming to switch the /s with the s so they now point around the X instead of towards it.
Ｊ±Ｎ±Ｎ
Jump to the top left of the desired output.
Ｔ⁷¦⁷
Trim the result to the desired size.

ＧL⁷-↙⁶X‖Ｂ↘¬‖Ｊ±Ｎ±ＮＴ⁷¦⁷
Try it online! Takes 0-indexed column and row as input. Explanation:
ＧL⁷-
Draw a triangle of -s.
↙⁶
Draw a line along the hypotenuse. (This is the wrong way around but we'll fix that later.)
X
Draw the X that shows the position of the wire. (Any other ASCII character could be used here of course.) This completes one eighth of the drawing.
‖Ｂ↘¬
Reflect three times (¬ = left + down) while transforming characters to almost complete the diagram.
‖
Reflect without transforming to switch the /s with the s so they now point around the X instead of towards it.
Ｊ±Ｎ±Ｎ
Jump to the top left of the desired output.
Ｔ⁷¦⁷
Trim the result to the desired size.
