Hi @Gogler_Sp_z_o_o, have you checked all steps, including the “Production” step provided by @samliew here: https://community.make.com/t/access-blocked-integromat-com-is-not-approved-by-advanced-protection/29079 ?
For the Google Business App, you only need the following redirect urls:
https://www.make.com/oauth/cb/google-custom
https://www.integromat.com/oauth/cb/google-custom
Can you give it a try and check if you have followed this step (I took the image from the post of @samliew):
