Audio Amp SHIM connection issues

Hi all

Recently bought a few of these for a project but having real trouble with the contacts. This will sit directly on a Pi 4b with an NFC hat above it but in order for me to get the audio out I need to twist the board slightly forwards to establish a strong contact with the pins. The docs claim no soldering required and I’d prefer not to if possible - is there a way round this? Something to establish a solid contact between the board and the pins without solder?

Thanks
