Problem installing Dorico Pro 5 in Mac (M1)

I bought Dorico and I am getting problems when installing it.
**“FabFilter Timeless 2.vst3” It cannot be opened because Apple cannot check for malicious software. I click Accept but continuos showing up same error.

I tried in Security to allow but same problem continues.
Someone same problem and fixed? I just bought and I want to use it, please.
