Idiot.

Soviets are structures and organisations produced by workers in struggle and which can form the basis of working class power including state power if socialist revolution is successful.

They provide more a much higher level of democracy for the workers in they are constant and represent active, involved, discussive democracy and on ongoing basis enabling working people to shape all decisions affecting their lives.

They are also working bodies in that they combine legislative with executive functions, enabling real ongoing accountability for delivery.

Far more democratic than say Parliamentary democracy in which all is required is for the voter to put an X in a box once every four or five years, handing over power to a parliamentary elite and a completely separate state organisation.

Translating them as "councils" really does nothing to describe their inherent working class function as you perfectly well know. In Britain e.g. during the General strike they were known as Councils of Action. Elsewhere they are often termed Popular Committees.

Factory Councils, Strike Committees, Support Groups (e.g. for the survivors of Grenfell) can be seen as Soviets in embryo i.e. workers coming together to actually address and resolve real issues and developing appropriate forms of organisation to take decisions and carry them out.

The SPGB (both versions) doesn't like the concept of Soviets or popular committees as they are in favour of parliamentary democracy in principle and as the means for establishing socialism. Actually, they don't like the idea of a real revolution, socialist or otherwise...
