Has anyone managed this, can they offer support!!!

I have primed my wallet to accept the BBS token and have some eth available for fees (not sure I have enough)

When I opt to stake my BBS tokens and connect a wallet I can select and use my Coinbase wallet but it will not allow me to connect my MetaMask wallet, I get the following lockup!!!

Can anyone help, advise, offer support, what am I doing wrong!!!

Many thanks in advance,🤞
