Remove square bracket from the Column Cells

Hi Team

Can you help to guide me how to remove the square bracket from the column cells using string manipulation.

Tried remove character not working as expected.

Input

[/Users/HubAdmin/Example Workflows/Basic Examples/TestSession(2)]

output

/Users/HubAdmin/Example Workflows/Basic Examples/TestSession(2)

Additionally can we able to insert one additional word (development) using “Join” expression into the above output as

/Users/HubAdmin/**Development**/Example Workflows/Basic Examples/TestSession(2)
