It’s been 25 to 30 years since chains could widely have the pin pushed out and be pushed back in again. 9 speed chain and on have universally used peened pins which should not be handled in that way. In general, quick links should be used and they are widely available for the 6/7/8 chains for older bikes or even modern bikes with 7 speed freewheels. They are also just easier to use.
