no matching function for call to 'Button2::Button2()' error when compiling

[Damien-Abot]

Hello,

I'm getting this error when trying to compile the code in arduino for my new TTGO t22_v1.0 20190612 version board.

`home/damien/Bureau/TTGO-T-Beam/TTGO-T-Beam.ino: In function 'void button_init()': TTGO-T-Beam:61:30: error: no matching function for call to 'Button2::Button2()' pBtns = new Button2 [args];

                          ^

I installed the button2 library from this address https://codeload.github.com/Xinyuan-LilyGO/TTGO-T-Beam/zip/master

Could you please help me ? Thanks,

This is the changed Button2 @Damien-Abot https://github.com/lewisxhe/Button2/tree/fed9e73972c8c3436dde5fe56d98ac7b7e7e9d41
